    Brooks, Aarti P.

    Cooperative learning allows individuals with varying abilities to work alongside their peers. Students are placed into achievement levels based on placement test scores. The Regular College Preparatory (RCP) level is a score of 59% or lower and Academic College Preparatory (ACP) level is a score of 60-92% on the placement test. The purpose of this study was to obtain 9th grade RCP students' perceptions of the student teams achievement divisions (STAD) approach which allows each member of a team to have a defined role in group work. The research questions addressed 9 th grade RCP students' perceptions of integrated STAD teams. Qualitative data from 6 RCP participants were collected from interviews and observations. Data were analyzed using typological analysis by creating codes and categories. Findings indicated that RCP students retained more content and enhanced their skills in communication, critical thinking, and problem solving. Teachers need to serve as guides to monitor motivation and enhance peer interaction. School administrators are advised to provide professional development opportunities allowing educators to learn how to incorporate cooperation for optimal student learning communication, negotiation, and problem solving.

    Preparatory education has been provided for both nursing students and teachers to understand the electronic patient record (EPR) since 2004 when EPR was introduced to the hospitals where students are allocated to undertake their work experience. First, the training and management board contacted our medical information department for an appointment and sent us a working group. They taught the nursing training staff how to use EPR and how to assign students to the proper patient record in the EPR system. Second, as preparatory education for the students, they explained the procedure for the use of EPR and the protection of personal information. Students practiced with training in the EPR system, focusing on the functions which are used frequently in practical tasks. As a result of this preparatory education, students understood the protection of personal information very well, although their understanding of the operation and management of the equipment was relatively poor and adversely affected their practice. We need to review our education contents more often. We also need to examine the present state of understanding of EPR and the problems of teaching in practical nursing training.

    2015-06-01

    The goals of this study were to (1) measure psychological, physiological, and behavioral indicators of stress, (2) assess the relationship between stress and student attitudes, and (3) explore coping behaviors in response to stress, among a sample of students in two academically high-achieving environments. Three hundred thirty-three students in grades 9 through 12 from two college-preparatory high schools completed a cross-sectional online survey that included the Students' Life Satisfaction Scale, School Attitude Assessment Questionnaire-Revised, and assessments for stress-related indicators, including eating, sleeping and exercise, and strategies they utilized for coping with stress. Students reported a high prevalence of physical and psychological correlates of stress, and related unhealthy behaviors such as widespread and chronic sleep deprivation and rushed meals. The results suggest areas to focus attention for identifying and addressing maladaptive responses to stress among high-achieving student populations.

    Full Text Available This study aims at providing a comprehensive account of the types of errors produced by Saudi EFL students enrolled in the preparatory year programe in their use of articles, based on the Surface Structure Taxonomies (SST of errors. The study describes the types, frequency and sources of the definite and indefinite article errors in writing compositions. Data were collected from written samples of 150 students. They were given one-and-a-half hours to write on one of four different descriptive topics. Analysis of  inter-lingual and intra-lingual sources of article errors revealed that the frequency of eliminating both the indefinite articles and the definite article was higher than the frequency of inserting and substituting one article with the other. The study also shows that errors of using ‘a’ were more common than errors of using ‘an’ and ‘the’ in the writing texts.  This result also indicates that L1 interference strongly influences the process of second language acquisition of the articles, having a negative effect on the learning process Pedagogical practices including comparison of article use in learners’ both language systems may improve learners’ ability to use the articles correctly in writing and the other language skills.

    Navigating puberty while developing independent living skills may render adolescents particularly vulnerable to stress, which may ultimately contribute to mental health problems (Compas, Orosan, & Grant, 1993; Elgar, Arlett, & Groves, 2003). The academic transition to high school presents additional challenges as youth are required to interact with a new and larger peer group and manage greater academic expectations. For students enrolled in academically rigorous college preparatory programs, such as the International Baccalaureate (IB) program, the amount of stress perceived may be greater than typical (Suldo, Shaunessy, & Hardesty, 2008). This study investigated the environmental stressors and psychological adjustment of 162 students participating in the IB program and a comparison sample of 157 students in general education. Factor analysis indicated students experience 7 primary categories of stressors, which were examined in relation to students' adjustment specific to academic and psychological functioning. The primary source of stress experienced by IB students was related to academic requirements. In contrast, students in the general education program indicated higher levels of stressors associated with parent-child relations, academic struggles, conflict within family, and peer relations, as well as role transitions and societal problems. Comparisons of correlations between categories of stressors and students' adjustment by curriculum group reveal that students in the IB program reported more symptoms of psychopathology and reduced academic functioning as they experienced higher levels of stress, particularly stressors associated with academic requirements, transitions and societal problems, academic struggles, and extra-curricular activities. Applied implications stem from findings suggesting that students in college preparatory programs are more likely to (a) experience elevated stress related to academic demands as opposed to more typical adolescent

    Background. Young people constitute a large number of population worldwide, and majority of this population group lives in developing countries. They are at high risk of engaging in risky sexual behaviors. These risk sexual behaviors predispose youths to several sexual and reproductive health problems like STIs, HIV, unwanted pregnancy, and abortion. So, this study was conducted to assess the magnitude of risky sexual behaviors and associated factors among Jiga high school and preparatory school students, northwest Ethiopia. Methodology. Institutional based cross-sectional study design was conducted among Jiga town high school and preparatory school students. A total of 311 students were included in the study. Systematic random sampling method was used to select study participants. Data was entered using EpiData version 3.1 and it was exported to SPSS version 22 for further analysis. Descriptive analysis and bivariate and multivariate analysis were also calculated to determine factors associated with risky sexual behavior. Result. Forty-eight (16%) of respondents reported that they had sexual intercourse. From those who start sex, 44 (14.7%) were involved in risky sexual behavior which could predispose them to sexual and reproductive health problems. More than half, 27 (56.3%), of respondents first sexual intercourse was before their eighteenth birthday. The mean age and SD of fist sexual initiation were 17.2 years old and 1.35 years, respectively. Factors associated with risky sexual behavior include respondents between the ages of 20 and 23 (AOR: 5, 95%, CI: 1.59–15.98), drinking alcohol (AOR: 2.48, 95% CI: 1.13–5.41), and having poor knowledge towards HIV/AIDS (AOR: 4.53, 95%, CI: 2.06–9.94). Conclusion. A large number of in-school youths are involved in risky sexual behaviors like early sexual initiation, having multiple sexual partners, inconsistence use of condom, and having sex with high risk partner (CSWs).

    Youth engage in risk sexual behavior due to insufficient knowledge of reproductive health and family planning. Youth sexual behavior is important not only because of the possible reproductive outcomes, but also because of sexually transmitted infections. The level of risks and sexual behaviors are different between male and female youth due to sexual exposure and socio-cultural factors. The aim of this study was to compare risky sexual behaviors and associated factors among male and female preparatory school (grades 11 and 12) students in Jimma Zone. A comparative cross-sectional study was conducted in 5 randomly selected preparatory schools of Jimma Zone. A total of 520 students were selected using simple random sampling technique. A structured, pretested and self-administered questionnaire was used to collect data. Both descriptive analysis and binary logistic regressions were performed on the data to understand risky sexual behaviors among students. Twenty-two (25.9%) of male and 25(21.6%) of female students had two or more sexual partners in the last six months. Eighty-three (32.3%), 113(43.5%) male and female students were sexually at risk in the last six months. Only 8(9.4%) of the male and 10(8.6%) of the female students used condom consistently in the last six months. Female students living away from their parents were 3 times more likely to be at risk than students living with their parents (OR 95%CI 3.0(1.48-6.34)). Female students who consumed alcohol were 7 times more likely to be at risk than those who did not consume alcohol (OR 95%CI 7.27(3.36-15.7)). Male students who consumed alcohol were 2.8 times more likely to be at risk than those who did not consumed alcohol (OR 95%CI, 2.81(1.3-6.06)). Male students who chewed khat were 4.6 times more likely to be at risk than students who did not chew khat (OR 95%CI, 4.58(1.95-10.76). Living arrangement, educational status of parents, family connectedness, alcohol consumption and khat-chewing were the major

The spread of HIV in any community is in part determined by the knowledge of attitude towards sexuality of its members and by their actual sexual practices. The aim of the study was to assess students' knowledge, attitudes and practices regarding HIV/AIDS and STDs in Gondar, North West Ethiopia. Methods A cross sectional study was conducted between February 1 to March 1, 2009 in preparatory high school students. Pre-tested questioner was used to generate the data and analysis was made by SPSS version 15. Chi -square value was calculated and p-value Results All the students had heard about AIDS before the interview. Knowledge on some aspect of the disease was quite low in the study group. Only half of the students knew that at present, AIDs is incurable and that HIV infection can be acquired through sexual contact with a 'familiar' person. Knowledge about STI was also quite low, 39% knew that pus in the urine is a symptom of STI and 45.4% knew that acquisition of other STIs is increases the chance of HIV transmission following unsafe sex with known cases. 25% of the study group had previous sexual intercourse and exposed at least one risk behavior. About 34% of the respondents had negative attitude towards AIDS and STDs. Conclusion Awareness about STDs and methods of prevention of HIV and STDs was low. More risk behavior was observed in male and those with alcohol and drugs of abuse.

    This study examined the effectiveness of a classroom-based intervention programme aimed at improving the oral language and emergent literacy skills of students from low socio-economic, culturally diverse backgrounds within their first formal year of schooling ("prep"). Data from 137 students were available for analysis. Participants were from three primary schools located in Queensland, Australia. Eight classes were allocated to intervention and two classes acted as a business as usual control. All students received literacy instruction as per the Australian Curriculum. However, the intervention group received 24 weeks of scripted, classroom-based, book-based intervention targeting code- and meaning-related emergent literacy skills. All students were assessed individually pre- and post-intervention on code-related measures (i.e. letter identification and phonological awareness) and meaning-related measures (i.e. vocabulary, oral narrative comprehension and retell). All students made significant improvement over time for all measures. Students in the intervention group showed significantly more progress than the business as usual group on all measures, except for letter identification and oral narrative comprehension. This classroom-based book-based intervention can improve the code- and meaning-related emergent literacy skills of prep students from low socio-economic backgrounds and provide these students with the building blocks for successful literacy acquisition.

  1. Preparatory attention in visual cortex.

    2017-05-01

    Top-down attention is the mechanism that allows us to selectively process goal-relevant aspects of a scene while ignoring irrelevant aspects. A large body of research has characterized the effects of attention on neural activity evoked by a visual stimulus. However, attention also includes a preparatory phase before stimulus onset in which the attended dimension is internally represented. Here, we review neurophysiological, functional magnetic resonance imaging, magnetoencephalography, electroencephalography, and transcranial magnetic stimulation (TMS) studies investigating the neural basis of preparatory attention, both when attention is directed to a location in space and when it is directed to nonspatial stimulus attributes (content-based attention) ranging from low-level features to object categories. Results show that both spatial and content-based attention lead to increased baseline activity in neural populations that selectively code for the attended attribute. TMS studies provide evidence that this preparatory activity is causally related to subsequent attentional selection and behavioral performance. Attention thus acts by preactivating selective neurons in the visual cortex before stimulus onset. This appears to be a general mechanism that can operate on multiple levels of representation. We discuss the functional relevance of this mechanism, its limitations, and its relation to working memory, imagery, and expectation. We conclude by outlining open questions and future directions. © 2017 New York Academy of Sciences.

    To compare the effectiveness of an internet-based training series with a traditional live classroom session in preparing pharmacy students to oversee a diabetes management program in community settings. Two cohorts of students were identified that prepared by utilizing a recorded online training exclusively, and two separate cohorts of students prepared by receiving only live classroom instruction. All students in the four cohorts were given a survey to evaluate the training sessions, and results were analyzed using the analysis of variance statistical test (ANOVA). Preceptors at the sites who interacted with students in all four cohorts were surveyed to evaluate which students appeared more prepared; these data were compared using paired t tests. Final assessment data for students in all four cohorts were analyzed using ANOVA. There were statistical differences between the two live training groups, with the second group finding the training to be more beneficial for preparing them, feeling the training length was appropriate and preferring the live modality for delivery. The two internet training cohorts were similar except for perceptions regarding the length of the online training. Comparing responses from those students who received live training with those receiving internet instruction demonstrated a statistical difference with the live groups rating the trainings as more helpful in preparing them for the clinics, rating the training as necessary, and rating their confidence higher in seeing patients. Preceptors rated the live training statistically higher than online training in preparing students. There was no difference between groups on their final site assessments. Live classroom training appears to be superior to the recorded internet training in preparing pharmacy students to oversee a diabetes management program in community settings.

The descriptive research method was used and data for the present study were collected with a five-point Likert-style scale. The study population consisted of ninety- seven students of English Language and Literature attending 2010 - 2011 academic year, spring term preparatory class 'Reading' course. The scale used in the study was developed by the researchers. The items were classified into four categories named „A1- A2 (elementary level reading skills‟, „B1 (intermediate B2 (upper intermediate level reading skills‟, „skills benefited from reading time‟ and „skills improved via reading‟. The scale was administered on totally 94 students. 26 of them were male, 68 were female. It was determined that reading comprehension skills were differed significantly in terms of gender variable and that female students‟ level was higher than that of males‟. Even though male students‟ levels were determined relatively lower, they were found to be better and more practical than female students in terms of using these skills actively and multi-dimensionally. While the level of reading comprehension skills was determined higher among the students who graduated from public high schools than the ones who graduated from schools admitting their students through entrance exams, the latter students were observed to be more skilled than the former ones in terms of using their reading skills.

    Bobrinsky, Nicolas

    A new ESA Programme on Space Situational Awareness (SSA) has been approved during the ESA Council at Ministerial level in November 2008. A preparatory phase is in progress, covering the timeframe 2009 -2012. It concentrates on the architectural design of the SSA System, its governance and data policy, as well as on the provision of precursor services based on the federation of existing National and European assets. A continuation of the SSA programme will be proposed at the next Ministerial Council for the years 2012 and onwards. The SSA Preparatory Programme covers three distinct segments, namely: -Space Surveillance and Tracking of artificial objects orbiting the Earth -Space Weather -Near Earth Objects Each of the above segments has a strong relation with Science and is supported by specific RD Programmes at National, EC and ESA levels. In this paper, the scientific aspects of the three SSA Segments are outlined and the following main topics developed: • Space Surveillance: statistical models of the evolution of the space debris population in Earth-bound orbits, study of active mitigation measures, impact analysis, tracking and char-acterisation principles based on radar and optical techniques. • Space Weather: awareness of the natural space environment, detection and forecasting of space weather effects and interferences, analysis of appropriate ground and space-based sensors for the monitoring of the Sun, the solar wind, the radiation belts, the magnetosphere and the ionosphere. • Near Earth Objects (NEOs): methods for determination of physical characteristics of newly discovered objects, study of appropriate sensors based on radar and optical techniques, iden-tification and ranking of collision risks of NEOs with the Earth, study of possible mitigation measures (e.g. Don Quichotes project). The research topics undertaken during the preparatory programme, as well as those foreseen during the next phase, possibly with a strong international cooperation

  4. Differential hemispheric modulation of preparatory attention.

    Fernández, Laura Gabriela; Siéroff, Eric

    2014-06-01

    Preparatory attention (PA) is the ability to allocate attention to a stimulus prior to its occurrence and is a crucial component of attentional control. We investigated the role of brain hemispheres in PA using an experimental test in which normal participants responded to a target that could appear in the right or the left visual fields, thus projecting to the left or the right hemispheres, while ignoring a central distractor that could appear in the preparatory phase preceding the target. This experimental test measures the ability of participants to modulate PA directed to a target location when the probability of a distractor occurrence varies across three blocks of trials (0%, 33%, 67%). The competition between distractors and target for PA should produce slower response times when the probability of distractors is high. Three experiments were conducted varying the temporal predictability of the target occurrence within a trial (high predictability in Experiments 1 and 3, and low predictability in Experiment 2), and the task used (location in Experiments 1 and 2, and detection in Experiment 3). We found that the modulation of PA by the expected probability of events was different in each visual field/hemisphere. Whereas the left hemisphere PA was influenced by the mere probability of events in each block of trials, the right hemisphere PA was mainly influenced by events with high temporal predictability. These results suggest that each hemisphere uses a different strategy to modulate PA when directed to a target location at the perceptual level of visual processing.

    2017-02-01

    Why do individuals mentally modify reality (e.g., "If it hadn't rained, we would have won the game")? According to the dominant view, counterfactuals primarily serve to prepare future performance. In fact, individuals who have just failed a task tend to modify the uncontrollable features of their attempt (e.g., "If the rules of the game were different, I would have won it"), generating counterfactuals that are unlikely to play any preparatory role. By contrast, they generate prefactuals that focus on the controllable features of their ensuing behavior (e.g., "If I concentrate more, I will win the next game"). Here, we test whether this tendency is robust and general. Studies 1a and 1b replicate this tendency and show that it occurs regardless of whether individuals think about their failures or their successes. Study 2 shows that individuals generate relatively few controllable counterfactuals, unless explicitly prompted to do so. These results raise some questions regarding the generality of the dominant view according to which counterfactuals mainly serve a preparatory function.

    2002-01-01

    The present research details 2 empirical tests within the context of the theory of planned behavior (I. Ajzen & T. Madden, 1986) of the assumption that preparatory behaviors (e.g., discussing safer sex, obtaining condoms) play a mediational role in the relation between psychological variables (e.g., attitudes toward safer sex, social norms about safer sex) and condom use. The assumption of the mediational role of preparatory behaviors is examined in sexually experienced samples from 2 different populations: inner-city high school students (N = 226) and college students (N = 160). The results suggest that the mediational role of preparatory behaviors is a highly significant one. Results indicate no gender differences with regard to the main mediational hypotheses. The methodological, theoretical, and practical implications and importance of these findings are discussed.

    Introduction: All medical schools in Saudi Arabia have English as the primary official medium of instruction. Most of the high school education, however, is delivered in Arabic and hence the transition to an English based learning environment tends to be difficult for some students. Our study aims to correlate English language proficiency with academic performance among medical students in their preparatory year. Methods: A cross-sectional study design was used. Test scores of 103 preparatory year students (54 female and 49 male) were analyzed after the students completed an English language course and medical introductory course in their preparatory year.

    All medical schools in Saudi Arabia have English as the primary official medium of instruction. Most of the high school education, however, is delivered in Arabic and hence the transition to an English based learning environment tends to be difficult for some students. Our study aims to correlate English language proficiency with academic performance among medical students in their preparatory year. A cross-sectional study design was used. Test scores of 103 preparatory year students (54 female and 49 male) were analyzed after the students completed an English language course and medical introductory course in their preparatory year.

  11. Reflecting on Language from ‘Sideways-on’: Preparatory and Non-Preparatory Aspects-Seeing

    Directory of Open Access Journals (Sweden)

    Reshef Agam-Segal

    2012-09-01

    Full Text Available Aspect-seeing, I claim, involves reflection on concepts. It involves letting oneself feel how it would be like to conceptualize something with a certain concept, without committing oneself to this conceptualization. I distinguish between two kinds of aspect-perception: 1. Preparatory: allows us to develop, criticize, and shape concepts. It involves bringing a concept to an object for the purpose of examining what would be the best way to conceptualize it. 2. Non-Preparatory: allows us to express the ingraspability of certain experiences. It involves bringing a concept to an object for the purpose of showing—per impossible—what it would take to properly capture one’s experience. I demonstrate the usefulness of the two kinds of aspect perception in making conceptual judgments, and in making moral and aesthetic judgments.

    Full Text Available Background: Adolescence is the period of transition from childhood to adulthood, and it occupies a crucial position in the human life. Nutrition for adolescents is important in which there was found changes in growth and hormones, activity, and food intake. The objective of the work: was to assess the nutritional status of preparatory school girls in Talkha city. Patients and methods: a descriptive cross- sectional study on a group of 500 students from the second and third year of the preparatory school girls at Talkha City in Dakahlia governorate , the tools used : 1- A self-administered questionnaire for assessing socio-demographic characteristics of students, anthropometric measurements included weight and height, nutritional health problems, assessing dietary knowledge, and eating habits.2 - An observational checklist to observe signs of malnutrition for the students. Results: majority of students, girls aged from 13- 14 years old and their mothers were house wife (69.6% &77.3% , Only less than half studied sample has correct knowledge about the balanced diet, the components of healthy diet, and the effect of healthy balanced diet on individual’s health (34.6 %&20%&78.4% respectively. Majority of students prefer eating food during watching TV., eating spices and salty food, and eating much candies (76.2% &74.6%& 73.6% respectively. The most common health problems were headache, GIT problems and dental decay respectively. Conclusion: only one quarter of the studied sample had correct and complete answers about balanced diet. The present study recommended that, health education for nutrition and healthy balanced diet should be integrated in the curriculum of preparatory school girls. Nurses and medical staff must play a significant role in screening, teaching, and guiding of adolescents about healthy balanced diet.

    2015-01-01

    A growing concern in emergency medical services (EMS) education is student attrition. Perchance, there is a population of nonmatriculate students lacking prerequisite academic skills or who are otherwise ill prepared for the unique requirements of the EMS profession. Consequently, addressing these issues could promote academic and occupational preparedness, thereby reducing emergency medical technician (EMT) course attrition. To measure the impact of a preparatory course designed to address academic and psychosocial skills affecting EMT course completion. We conducted a retrospective analysis of a 24-hour preparatory course using a before-and-after nonexperimental design. The course included the EMT preparatory curriculum, program orientation, work-force-preparedness skills, and an academic skills assessment. All students who were enrolled in an EMT course at a single study site between July 2008 and December 2011 were included. Chi-square analysis was performed on attrition categories defined by CoAEMSP (Academic, Disciplinary, Attendance, Health, Financial, Personal, Never Attended) and state exam categories (Airway, Medical, Trauma, Operations, Pediatrics, Preparatory, Assessment). A logistic regression model calculated the odds ratio (OR) of course completion as a function of preparatory course completion while controlling for demography. The historical control group consisted of 117 (58.5%) students enrolled prior to implementation of the preparatory course, while the remaining 83 (41.5%) students in the intervention group completed the course. Overall attrition was 115 (57.5%) students, with lower rates observed in the intervention group (32.5 vs. 75.2%, p Attended (1.2 vs. 14.5%, p Students who took the preparatory course were more likely to achieve course completion (OR = 5.17, p rate despite showing little difference in individual categories. Students who participated in an EMS preparatory course were 5 times more likely to achieve course completion and

    Hewko, Sarah J; Cooper, Sarah L; Cummings, Greta G

    2015-01-01

    Moral reasoning skills, associated with the ability to make ethical decisions effectively, must be purposively fostered. Among health professionals, enhanced moral reasoning is linked to superior clinical performance. Research demonstrates that moral reasoning is enhanced through dedicated, discussion-based ethics education offered over a period of 3-12 weeks. Current dietetic students and practicing dietitians seeking to strengthen their moral reasoning skills can undertake elective ethics education. Further research within dietetic preparatory programs is warranted to better inform the development and implementation of ethics courses.

    1982-12-01

    On the premiss that an important aim of the initial phase of supervision of the neophyte group psychotherapist is to convert a new and threatening situation into an old and familiar one, the function of a preparatory interview--whose focus was the therapist's set of expectations about his impending experience of leading a group--was examined. The findings of a series of 26 interviews point to the need for a systematic controlled study to test the effects of a preparatory interview of the trainee therapist on group process and leadership behaviour.

  18. The Impact of a Modified Cooperative Learning Technique on the Grade Frequencies Observed in a Preparatory Chemistry Course

    Science.gov (United States)

    Hayes Russell, Bridget J.

    This dissertation explored the impact of a modified cooperative learning technique on the final grade frequencies observed in a large preparatory chemistry course designed for pre-science majors. Although the use of cooperative learning at all educational levels is well researched and validated in the literature, traditional lectures still dominate as the primary methodology of teaching. This study modified cooperative learning techniques by addressing commonly cited reasons for not using the methodology. Preparatory chemistry students were asked to meet in cooperative groups outside of class time to complete homework assignments. A chi-square goodness-of-fit revealed that the final grade frequency distributions observed were different than expected. Although the distribution was significantly different, the resource investment using this particular design challenged the practical significance of the findings. Further, responses from a survey revealed that the students did not use the suggested group functioning methods that empirically are known to lead to more practically significant results.

    2013-04-01

    Full Text Available This study investigated if receiving cognitive and metacognitive reading strategy training explicitly would make a difference in the University preparatory class students’ reading comprehension. From the instructors’ aspect, the instructors’ views about and approaches to teaching reading strategies were investigated and compared with each other. 83 students and 4 instructors particapated to this mix-method study. Following the Solomon-four-group design the participants were divided into 2 research and 2 comparison groups. Data collection methods were pre-post reading comprehension test, CRSUS, MRSUS, TRSUS, self-evaluation checklists, interviews and classroom observations. The results of the study show that there is no significant difference in the reading comprehension of the comparison and research group students at the end of the term. For the instructors, the results indicate that the research group instructors had tendency to use more reading strategies. The paper concluded with implications and suggestions for the future research.

    2017-01-01

    Evidence to date suggests heterogeneity in the effects of implementation intentions on health behaviour, including diet. Additional variables and study designs may impact on their effectiveness. Preparatory action, such as making sure fruits are available for consumption, may be an important additional variable. Likewise, most implementation intention research has focused on changes in general intake, yet implementation intention instructions typically require participants to consider behaviour in specific situations. Little is known on how implementation intentions impact situation-specific intake. The present study sought to add to the evidence base by comparing (1) the effects of action planning instructions versus preparatory planning instructions on (2) both situation-specific (as formulated in the implementation intention instruction) and general intake of fruits and in-between meal snack intake frequency. Fruit intake was assessed in average pieces per day, whereas snacking intake was assessed as average frequency in days per week. Using non-probability sampling, 243 undergraduate students who intended to have a healthy diet were randomized to either a standard information control condition, an action planning condition, or a preparatory planning condition. Planning manipulations were based on previous work. Two weeks later, general and situation-specific intake was assessed again in 181 participants. Data were analysed using 2 (time) x 3 (conditions) analyses of variance. Results showed that both planning manipulations were successful in decreasing snack intake frequency in the specified situation, with larger effect sizes for the action planning condition than for the preparatory planning condition. No effects were found on general snack intake frequency or fruit intake. Future planning interventions should more explicitly compare changes in situational and general intake, as well as simultaneously assessed decreases in unhealthy intake and increases in

    Now in its fourth year, the AAS Oral History Project has interviewed over 80 astronomers from all over the world. Led by the AAS Historical Astronomy Division (HAD) and partially funded by the American Institute of Physics Niels Bohr Library and ongoing support from the AAS, volunteers have collected oral histories from astronomers at professional meetings starting in 2015, including AAS, DPS, and the IAU general assembly. Each interview lasts one and a half to two hours and focuses on interviewees’ personal and professional lives. Questions include those about one’s family, childhood, strong influences on one’s scientific career, career path, successes and challenges, perspectives on how astronomy is changing as a field, and advice to the next generation. Each interview is audio recorded and transcribed, the content of which is checked with each interviewee. Once complete, interview transcripts are posted online as part of a larger oral history library at https://www.aip.org/history-programs/niels-bohr-library/oral-histories. Future analysis will reveal a rich story of astronomers and will help the community address issues of diversity, controversies, and the changing landscape of science. We are still recruiting individuals to be interviewed from all stages of career from undergraduate students to retired and emeritus astronomers. Contact Jarita Holbrook to schedule an interview or to find out more information about the project (astroholbrook@gmail.com). Also, contact Jarita Holbrook if you would like to become an interviewer for the project.

    2017-06-01

    Full Text Available Smartboards, which are now widely used in the teaching and learning process in Saudi Arabia, have turned the traditional environments of the classrooms, especially the EFL classrooms to be more interesting and encouraging. Literature reviews suggest that Saudi students usually lack motivation for studying English as a foreign language. This study tends to investigate the impact of Smartboards on preparatory year EFL learners motivation at a Saudi university. Two intact groups were selected, in which one was termed as experimental and the second as control group. The experimental group was taught using the Smartboard while the control group was taught with the traditional whiteboard, pen and book method. The treatment was given for seven weeks. A questionnaire was administered to both the groups at the beginning and the end of the study. The data was analysed using the SPSS and the results showed that there was significant difference between the experimental and control groups in terms of motivation.

    2016-12-01

    Full Text Available The aim of this case study is to analyze the supplementary instructional materials, namely worksheets, used in an English preparatory school in one of the Turkish universities. The data were gathered from the materials development unit of the school. Using the content analysis method, worksheets from 2015 spring and 2016 spring terms were analyzed. The findings revealed that most worksheets included decontextualized, repetitive grammar activities though the theme-based course book included integrated skills activities, appealing various learning styles. It was also observed that students were evaluated based on their proficiency in basic four skills while they studied mostly grammar based worksheets. As a result, a shift to a more eclectic method which caters for all learning styles and equally includes all skills is suggested to the school board.

  14. Preparatory effects of distractor suppression: evidence from visual cortex.

    Directory of Open Access Journals (Sweden)

    Jaap Munneke

    Full Text Available Spatial selective attention is the mechanism that facilitates the selection of relevant information over irrelevant information in the visual field. The current study investigated whether foreknowledge of the presence or absence of distractors surrounding an impending target stimulus results in preparatory changes in visual cortex. We cued the location of the target and the presence or absence of distractors surrounding the target while changes in blood oxygen level dependent (BOLD signals were measured. In line with prior work, we found that top-down spatial attention resulted in an increased contralateral BOLD response, evoked by the cue throughout early visual cortex (areas V1, V2 and V3. In addition, cues indicating distractor presence evoked a substantial increase in the magnitude of the BOLD signal in visual area V3, but not in V2 or V1. This study shows that prior knowledge concerning the presence of a distractor results in enhanced attentional modulation of visual cortex, in visual areas where neuronal receptive fields are large enough to encompass both targets and distractors. We interpret these findings as evidence that top-down attentional control processes include active preparatory suppression mechanisms for irrelevant, distracting information in the visual scene.

    2015-07-01

    The authors tested whether engaging in expansive (vs. contractive) "power poses" before a stressful job interview--preparatory power posing--would enhance performance during the interview. Participants adopted high-power (i.e., expansive, open) poses or low-power (i.e., contractive, closed) poses, and then prepared and delivered a speech to 2 evaluators as part of a mock job interview. All interview speeches were videotaped and coded for overall performance and hireability and for 2 potential mediators: verbal content (e.g., structure, content) and nonverbal presence (e.g., captivating, enthusiastic). As predicted, those who prepared for the job interview with high- (vs. low-) power poses performed better and were more likely to be chosen for hire; this relation was mediated by nonverbal presence, but not by verbal content. Although previous research has focused on how a nonverbal behavior that is enacted during interactions and observed by perceivers affects how those perceivers evaluate and respond to the actor, this experiment focused on how a nonverbal behavior that is enacted before the interaction and unobserved by perceivers affects the actor's performance, which, in turn, affects how perceivers evaluate and respond to the actor. This experiment reveals a theoretically novel and practically informative result that demonstrates the causal relation between preparatory nonverbal behavior and subsequent performance and outcomes.

  17. Tracking chemistry self-efficacy and achievement in a preparatory chemistry course

    Garcia, Carmen Alicia

    Self-efficacy is a person's own perception about performing a task with a certain level of proficiency (Bandura, 1986). An important affective aspect of learning chemistry is chemistry self-efficacy (CSE). Several researchers have found chemistry self-efficacy to be a fair predictor of achievement in chemistry. This study was done in a college preparatory chemistry class for science majors exploring chemistry self-efficacy and its change as it relates to achievement. A subscale of CAEQ, Chemistry Attitudes and Experiences Questionnaire (developed by Dalgety et al, 2003) as well as student interviews were used to determine student chemistry self-efficacy as it changed during the course. The questionnaire was given to the students five times during the semester: in the first class and the class before each the four tests taken through the semester. Twenty-six students, both men and women, of the four major races/ethnicities were interviewed three times during the semester and events that triggered changes in CSE were followed through the interviews. HLM (hierarchical linear modeling) was used to model the results of the CSE surveys. Among the findings, women who started at significantly lower CSE than men accomplished a significant gain by the end of the semester. Blacks' CSE trends through the semester were found to be significantly different from the rest of the ethnicities.

    The GAUDI database (Ground-based Asteroseismology Uniform Database Interface) is a preparatory archive for the COROT (Convection, Rotation, and Planetary Transits) mission developed at the Laboratorio de Astrofísica Espacial y Física Fundamental (Laboratory for Space Astrophysics and Theoretical Physics, Spain). Its intention is to make the ground-based observations obtained in preparation of the asteroseismology program available in a simple and efficient way. It contains spectroscopic and photometric data together with inferred physical parameters for more than 1500 objects gathered since 1998 January 1998 in 6 years of observational campaigns. In this paper, the main functions and characteristics of the system are described. Based on observations collected at La Silla (ESO proposals 67.D-0169, 69.D-0166, and 70.D-0110), Telescopio Nazionale Galileo (proposal 6-20-068), Observatoire de Haute-Provence, the South African Astronomical Observatory, Tautenburg Observatory, and Sierra Nevada Observatory.

    Full Text Available This paper seeks to investigate the types of conflicts that occur during collaborative writing among a group of ESL/EFL upper intermediate students in a preparatory programme. It also examines how these conflicts are resolved among the group members. A group consisting of four students was chosen for this study. Audio and video-recordings of collaborative sessions, semi-structured interviews and students’ journal were used in the data collection process. The results of this qualitative study showed that there were two prominent types of conflicts that occurred during the collaboration, namely, substantive conflict and affective conflict. Substantive conflict was found to be useful as the group was able to voice disagreements and consider alternative ideas. However, there was more evidence of affective conflict where the group had misunderstandings and differences due to personal views about group members. The study shows that the success of collaborative writing depends very much on how conflict is handled and resolved among the members.Keywords: collaborative writing, substantive conflict, affective conflict, argumentative essay, ESL/EFL learners

    Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual's level of self-efficacy. A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model. Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours. Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity.

    Necessary restorative requirements for full coverage are adequate axial wall height of the preparation for retention as well as sufficient vertical width of sound tooth structure cervically for the crown margins. In cases where adequate healthy tooth structure does not exist coronally to the epithelial attachment due to various crown damages, the margins of the crown might traumatize the periodontal attachment and the periodontium will be jeopardized iatrogenically. Teeth with inadequate axial Reight of the clinical crown, subgingival caries, vertical or horizontal fractures will require surgical crown lengthening procedures before prosthetic treatment is performed. These procedures may either involve only the soft tissues or bone remodeling as well. Irrespective of the procedure, crown lengthening must be performed with the objective of at least 3 mm. of healthy tooth structure coronally to the bone. This width will permit the formation of a new dentinogingival junction and the existence of 1-2 m.m. of sound tooth structure coronally to the new attachment line for the construction of a biologically acceptable crown margin. The purpose of this article is to discuss the clinical problem and underline the importance of crown lengthening procedures as a preparatory step for prosthetic treatment in fixed partial dentures.

  7. Dissecting patterns of preparatory activity in the frontal eye fields during pursuit target selection.

    We investigated the composition of preparatory activity of frontal eye field (FEF) neurons in monkeys performing a pursuit target selection task. In response to the orthogonal motion of a large and a small reward target, monkeys initiated pursuit biased towards the direction of large reward target motion. FEF neurons exhibited robust preparatory activity preceding movement initiation in this task. Preparatory activity consisted of two components, ramping activity that was constant across target selection conditions and a flat offset in firing rates that signaled the target selection condition. Ramping activity accounted for 50% of the variance in the preparatory activity and was linked most strongly, on a trial-by-trial basis, to pursuit eye movement latency rather than to its direction or gain. The offset in firing rates that discriminated target selection conditions accounted for 25% of the variance in the preparatory activity, and was commensurate with a winner-take-all representation signaling the direction of large reward target motion rather than a representation that matched the parameters of the upcoming movement. These offer new insights into the role the frontal eye fields play in target selection and pursuit control. They show that preparatory activity in the FEF signals more strongly when to move rather than where or how to move, and suggest that structures outside the FEF augment its contributions to the target selection process.

    Recommendation systems have been widely used in internet activities whose aim is to present the important and useful information to the user with little effort. Course Recommendation System is system which recommends to students the best combination of courses in engineering education system e.g. if student is interested in course like system programming then he would like to learn the course entitled compiler construction. The algorithm with combination of two data mining algorithm i.e. combination of Expectation Maximization Clustering and Apriori Association Rule Algorithm have been developed. The result of this developed algorithm is compared with Apriori Association Rule Algorithm which is an existing algorithm in open source data mining tool Weka.

    Preparatory sensory information (PSI) has been found to have significant effects in reducing distress, tension, restlessness, negative moods, and anxiety, and also in reducing length of postoperative hospitalization during various threatening medical events, but no evidence has demonstrated the effect of PSI on a patient during ICU hospitalization. On the basis of Lazarus' theory, a structural equation model was developed to examine the role of the nursing intervention, PSI, as a significant factor influencing patients' processes of cognitive appraisals and coping, adaptational responses, and patient care outcomes during ICU hospitalization. The analytical model examined the net effect of PSI on outcomes, controlling for the effects of mastery, interpersonal trust, social support, socioeconomic status, severity of illness, age, and gender. A quasi-experiment was executed in four large acute care hospitals. Data were collected from 41 subjects in the control group and from 42 in the treatment group receiving PSI before ICU admission. Structural equation modeling was employed to test the proposed analytic model. The initial tests of model fit indicate that the original model did not fit the data well with GFI = 0.85, AGFI = 0.76, RMSEA = 0.059, p_close = 0.28, and critical N = 78. A revised model was developed, and the fit indices suggested an adequate fit with GFI = 0.90, AGFI = 0.84, RMSEA = 0.00, p_close = 0.89, and critical N = 109. These findings provide empirical support for Lazarus' theory on stress, appraisal, and coping. The findings also verify the beneficial effects of the nursing intervention of PSI on ICU patients.

    The deployment of spatial attention induces retinotopically specific increases in neural activity that occur even before a target stimulus is presented. Although this preparatory activity is thought to prime the attended regions, thereby improving perception and recognition, it is not yet clear whether this activity is a manifestation of signal enhancement at the attended locations or suppression of interference from distracting stimuli (or both). We investigated the functional role of these preparatory shifts by isolating a distractor suppression component of selection. Behavioral data have shown that manipulating the probability that visual distractors will appear modulates distractor suppression without concurrent changes in signal enhancement. In 2 experiments, functional magnetic resonance imaging revealed increased cue-evoked activity in retinotopically specific regions of visual cortex when increased distractor suppression was elicited by a high probability of distractors. This finding directly links cue-evoked preparatory activity in visual cortex with a distractor suppression component of visual selective attention.

She presented a very practical overview of the advice in her book (which this job-searching Astrobiter highly recommends). Her target audience is postdocs and graduate students who are finishing their PhDs and applying for tenure-track jobs. Karens background is in the social sciences, but she has worked with many scientists and her expertise easily transferred. Much of her writing advice also applies for undergraduates who are writing research statements and proposals to apply to graduate school.

Karen was also surprised that the majority of professional astronomers at the AAS meeting carry backpacks, because she typically advises against bringing a backpack to a job interview or

    Full Text Available It cannot be said that education today in institutions is better than the previous century. Because in the past, students’ mind was not as full of time-consuming things like spending enormous time in front of a computer or a television as today. Subsequently, teachers used to concentrate their job well and students used to focus on the study better because there was nothing serious except studying. On the other hand, it can be said that the youth today are not eager to learn as yesterday. Because of the fact that they are economically free and supported, they do not worry about failing in the exams supposing that they can possess the questions somehow easily and pass the exams. As a result, they think that whatever they want, they can simply gain without pain. Doing homework or extra studies are a torture from students' perspective. As lecturers we are we have to find much more tactics to motivate students in this education era. Hence, extracurricular activities might play a great role for motivating them to study and on their study achievement if they are used in institutions effectively. In my research article educators’ observations and extracurricular activities’ positive impact on weak language learners will be mentioned.

LAT stands for Large Area Telescope, an instrument on board the Fermi gamma-ray space observatory that scans the entire sky every three hours. Ajello described the contents of the 2FHL catalog: 360 gamma-ray sources, of which 75% are blazars (distant galactic nuclei with jets pointed toward us), 11% are sources within the galaxy, and the remaining 14% are unknown. With this catalog, Fermi has expanded into higher energies than ever before, providing the first map of the 50 GeV 2 TeV sky.

OMeara showed us the emission spectrum from a distant quasar, which displays abrupt absorption by a cloud of gas located at a redshift of z~3.5. Absorption by gas clouds is not unusual but what is unusual is that this cloud is extremely metal-poor, with only 1/2500th solar metallicity. This is the lowest heavy-element content ever measured, and a sign that the cloud might have been enriched by Population III stars the theoretical first population of stars, which were born when gas in the universe was still pristine.

The statistical grouping of the research includes the admitted students and eventually 483 female and 53 male students in seven provinces constituted the statistical samples of the study. It was concluded that the separation plan is facing numerous problems at the current juncture. The relevant procedures and the manner of inter-organizational cooperation are not sufficient and the admission process has to undergo changes. Welfare facilities at the centers are not sufficient and keeping the students at the dorms for a long time will bring about many problems for them. Hence, the existence of a strong observation system as well as social workers are among the requisites for keeping up the implementation of the plan. Moreover, attention must be paid to other substitute methods so that the student would be able to study in his normal living environment and in this way reduce possible risks.

    Research objective was to compare the efficiency of different preoperative preparatory programs which had been used for anxiety decrease in Pediatric patients before oral cavity sanation with general anaesthesia. Two preparatory programs were used. In the first program patients were informed about the treatment they were undergoing. Patients visited the operating unit and watched the videos about forthcoming procedure (group of Information Technologies (IT), n = 82). The second program included the tutorials (face mask use, acquaintance with equipment alarms etc.) in addition to Information Technologies (group of lnformation Technologies and tutorials (ITT) n = 83). Information Technologies and tutorials were not used in the control group (n = 86). Both used programs were effective. ITT program was the most effective.

    Grief and depression present similarly in patients who are dying. Conventional symptoms (e.g., frequent crying, weight loss, thoughts of death) used to assess for depression in these patients may be imprecise because these symptoms are also present in preparatory grief and as a part of the normal dying process. Preparatory grief is experienced by virtually all patients who are dying and can be facilitated with psychosocial support and counseling. Ongoing pharmacotherapy is generally not beneficial and may even be harmful to patients who are grieving. Evidence of disturbed self-esteem, hopelessness, an active desire to die and ruminative thoughts about death and suicide are indicative of depression in patients who are dying. Physicians should have a low threshold for treating depression in patients nearing the end of life because depression is associated with tremendous suffering and poor quality of life.

But, as reported by James Ingalls (Spitzer Science Center, Caltech), observers are circumventing this issue by using what they call the staring mode (avoiding large pointing jumps) and an algorithm to pick sweet spot pixels. Moreover, the results from the IRAC Data Challenge are helping to better understand its behavior.

    Full Text Available After the terrorist attack at theBostonMarathon, Federal and Republican executive bodies took increased security measures during the XXVII World Summer Universiade inKazan. Bodies and Organizations of the Federal Service for Surveillance on Consumer Rights Protection and Human Well-being (Rospotrebnadzor were participants of all preparatory activities and directly provided security of the Student Games inKazan. This report analyzes the experience of providing radiation safety by Rospotrebnadzor experts at the stage of preparation for the Universiade. So far, Rospotrebnadzor organizations had no experience of providing radiation safety of such large-scale events. Analysis of the performed work with account for both positive and negative experiences is especially important in the context of preparations for the safety providing of the Olympic Winter Games inSochiin 2014.

  2. Pupil size reveals preparatory processes in the generation of pro-saccades and anti-saccades.

    2015-04-01

    The ability to generate flexible behaviors to accommodate changing goals in response to identical sensory stimuli is a signature that is inherited in humans and higher-level animals. In the oculomotor system, this function has often been examined with the anti-saccade task, in which subjects are instructed, prior to stimulus appearance, to either automatically look at the peripheral stimulus (pro-saccade) or to suppress the automatic response and voluntarily look in the opposite direction from the stimulus (anti-saccade). Distinct neural preparatory activity between the pro-saccade and anti-saccade conditions has been well documented, particularly in the superior colliculus (SC) and the frontal eye field (FEF), and this has shown higher inhibition-related fixation activity in preparation for anti-saccades than in preparation for pro-saccades. Moreover, the level of preparatory activity related to motor preparation is negatively correlated with reaction times. We hypothesised that preparatory signals may be reflected in pupil size through a link between the SC and the pupil control circuitry. Here, we examined human pupil dynamics during saccade preparation prior to the execution of pro-saccades and anti-saccades. Pupil size was larger in preparation for correct anti-saccades than in preparation for correct pro-saccades and erroneous pro-saccades made in the anti-saccade condition. Furthermore, larger pupil dilation prior to stimulus appearance accompanied saccades with faster reaction times, with a trial-by-trial correlation between dilation size and anti-saccade reaction times. Overall, our results demonstrate that pupil size is modulated by saccade preparation, and neural activity in the SC, together with the FEF, supports these findings, providing unique insights into the neural substrate coordinating cognitive processing and pupil diameter.

    The prospect of gaining money is an incentive widely at play in the real world. Such monetary motivation might have particularly strong influence when the cognitive system is challenged, such as when needing to process conflicting stimulus inputs. Here, we employed manipulations of reward-prospect and attentional-preparation levels in a cued-Stroop stimulus conflict task, along with the high temporal resolution of electrical brain recordings, to provide insight into the mechanisms by which reward-prospect and attention interact and modulate cognitive task performance. In this task, the cue indicated whether or not the participant needed to prepare for an upcoming Stroop stimulus and, if so, whether there was the potential for monetary reward (dependent on performance on that trial). Both cued attention and cued reward-prospect enhanced preparatory neural activity, as reflected by increases in the hallmark attention-related negative-polarity ERP slow wave (contingent negative variation [CNV]) and reductions in oscillatory Alpha activity, which was followed by enhanced processing of the subsequent Stroop stimulus. In addition, similar modulations of preparatory neural activity (larger CNVs and reduced Alpha) predicted shorter versus longer response times (RTs) to the subsequent target stimulus, consistent with such modulations reflecting trial-to-trial variations in attention. Particularly striking were the individual differences in the utilization of reward-prospect information. In particular, the size of the reward effects on the preparatory neural activity correlated across participants with the degree to which reward-prospect both facilitated overall task performance (shorter RTs) and reduced conflict-related behavioral interference. Thus, the prospect of reward appears to recruit attentional preparation circuits to enhance processing of task-relevant target information.

    The processes involved in tritium transfer in crops are complex and regulated by many feedback mechanisms. A full mechanistic model is difficult to develop due to the complexity of the processes involved in tritium transfer and environmental conditions. First, a review of existing models (ORYZA2000, CROPTRIT and WOFOST) presenting their features and limits, is made. Secondly, the preparatory steps for a robust model are discussed, considering the role of dry matter and photosynthesis contribution to the OBT (Organically Bound Tritium) dynamics in crops.

  5. Effects of long-term blindness on preparatory emg modulation in humans performing landing movements.

    2011-10-01

    To investigate the long-term effect of blindness on the task of leaping down to a lower landing surface, five blind individuals were compared with 10 sighted individuals who performed landing movements with and without sight. Participants performed six consecutive drop-landings from four different heights, during which the prelanding modulation of EMG timing and amplitude in four lower-limb muscles were recorded. Analysis showed that blind individuals showed specific prelanding EMG modulation, suggesting that long-term dependence on somesthetic and vestibular cues leads to different preparatory measures for vertical falls.

  6. Effect of Cotton Fibers and Their Trash Characteristics on the Performance of Spinning Preparatory Processes

    Directory of Open Access Journals (Sweden)

    Dr. (Mrs. Tasnim N. Shaikh

    2016-06-01

    Full Text Available Technological revolution in the age old cotton textile industry has made spinning preparatory section as a control centre for quality and economy of the outgoing product. Spinners have to chase these goals by cleaning the cotton mix without detoriating feed cotton characteristics and undue increase in the waste levels at higher productivity level. The successful efforts demand through investigation of the cotton fibers and their trash characteristics as well as identification of their best fit interrelationship with process parameters. Set of experimentations done in this direction are described in this paper as case study.

    We previously demonstrated the relationship between sidestepping performance and the preparatory state of ground reaction forces (GRFs). The present study investigated the effect of the preparatory state of GRFs on defensive performance in 1-on-1 subphase of basketball. Ten basketball players participated in 1-on-1 dribble game of basketball. The outcomes (penetrating and guarding) and the preparatory state of GRFs (non-weighted and weighted states, i.e. vertical GRFs below and above 120% of body weight, respectively) were assessed by separating the phases. In the non-weighted state and the weighted state to determine the outcome, the probability of successful guarding was 78.8% and 29.6%, respectively. The non-weighted state prevented delay of the defensive step in the determination phase. Both the non-weighted and weighted states, immediately before the determination phase, were likely to change to the weighted state in the determination phase; during this time, the defender's preparatory state would be destabilised, presumably by the dribbler's movement. These results revealed that the preparatory GRFs before the defensive step help to explain the outcome of the 1-on-1 subphase, and suggest a better way to prevent delaying initiation of the defensive step and thereby to guard more effectively against a dribbler.

    Full Text Available Purpose: to substantiate a methodology of high-speed and strength qualities development of young biathlonists aged 14–15 during the preparatory period. Material and Methods: young biathlonists aged 14–15 from control and experimental groups took part in the research. There were 12 athletes in each group. Pedagogical methods and methods of mathematical statistics were used in the work. Pedagogical methods of researches were used for level definition of high-speed and strength qualities development of young biathlonists. Results: reliable increase of motive qualities and polydynamometry results testing of young biathlonists from the experimental group due to implementation of the experimental methodology in the preparatory period is established. Conclusions: application of the developed complexes in the preparatory period in the experimental group of young biathlonists aged 14–15 allows to raise indices of motive qualities and polydynamometry testing statistically significantly.

    This laboratory study examined differential effects of television broadcasts of terrorism on viewers' anxiety according to their actual exposure history, and differential efficacy of a preparatory intervention in moderating elevated anxiety for high or low actual exposure. Participants were 80 young Israeli adults, randomly allocated to a terrorism or non-terrorism media broadcast, and for each type of exposure, to a preparatory or control intervention. Actual political violence and terrorism exposure history was assessed, and anxiety measured explicitly and indirectly prior and subsequent to the intervention and media exposure manipulation. Results showed that in the terrorism media exposure, participants with high more than low actual political life events (PLE) exposure showed higher post-test levels of indirectly measured anxiety. Clinical intervention before the terrorism media exposure moderated indirectly measured anxiety among participants with high PLE exposure, but increased anxiety for low PLE. Findings outline preparatory measures that could maximize coping for the high PLE actual exposure at-risk sector.

    2013-06-01

    Coordination between networks of brain regions is important for optimal cognitive performance, especially in attention demanding tasks. With the event-related optical signal (a measure of changes in optical scattering because of neuronal activity) we can characterize rapidly evolving network processes by examining the millisecond-scale temporal correlation of activity in distinct regions during the preparatory period of a response mode switching task. Participants received a precue indicating whether to respond vocally or manually. They then saw or heard the letter "L" or "R," indicating a "left" or "right" response to be implemented with the appropriate response modality. We employed lagged cross-correlations to characterize the dynamic connectivity of preparatory processes. Our results confirmed coupling of frontal and parietal cortices and the trial-dependent relationship of the right frontal cortex with response preparation areas. The frontal-to-modality-specific cortex cross-correlations revealed a pattern in which first irrelevant regions were deactivated, and then relevant regions were activated. These results provide a window into the subsecond scale network interactions that flexibly tune to task demands.

    Lopez, C

    1994-01-01

    This address by the Peruvian delegation to the Third Preparatory Committee Meeting for the International Conference on Population and Development focuses on four points in the proposed Plan of Action that might require further development. First, the link between drug trafficking and environmental degradation should be recognized. Cultivation of narcotic plants contributes to deforestation of the tropical forest and contamination of rivers, and along with terrorism has caused considerable population movement in Peru. The second point is that widespread poverty, limited investment in human capital, insufficient institutional capacity, and the external debt burden of the developing countries are clearly interrelated with sociodemographic processes and decisively affect the capacity of the nation to implement population policies and programs as a function of current and future international commitments. The third point is that, in the area of information, education, and communication, attention should be given to the entire life cycle and the entirety of themes related to population. Finally, coordinated programs between public and private institutions and nongovernmental organizations at the national level, and between the U.N. Population Fund, the Population Commission, and the Commission on Sustainable Development at the international level, should be organized to assure effective follow-up on Plan of Action proposals and agreements. Peru has participated in a wide variety of international conferences and activities related to population, and was a major participant in the subregional preparatory conference of the Andean nations.

    2016-07-01

    Full Text Available The present study attempts to find out the practical barriers to technology integration in an Arab EFL scenario, particularly in the context of Preparatory Year English courses. The practical barriers to CALL practices are multifaceted and vary according to contexts. In this mixed method study, 50 ESL teachers were surveyed using a 5-point Likert-scale questionnaire. The questionnaire focused on the pedagogical, technological, personal and administrative barriers to CALL integration in an EFL context. In addition, 21 teachers participated in the focus group discussion. Overall, the survey results found that the barriers influencing CALL integration in the study context were moderate. However, lack of administrative support, inadequate training, and absence of suitable materials were found as significant barriers to CALL integration. The focus group discussion reiterated the issues and suggested practical solutions for maximization of CALL practices. The study suggests a holistic administrative approach to solve the barriers to CALL integration.

    刑法对犯罪预备没有规定独立的法定刑,只是可以比照既遂犯从轻、减轻或者免除处罚。但当刑法分则将犯罪预备行为规定为独立的罪名时,此时行为已是一种实行状态而非预备。预备行为实行化将一罪的预备行为规定为独立的预备罪,虽然对法益的保护提前了,但扩大了刑法的处罚范围,因此有必要对其进行合理的限定。犯罪预备是一种非实行行为,预备行为实行化之后,准备工具、制造条件的预备行为提升为实行行为,其就存在未遂的可能,也即独立预备罪的未遂。预备行为同时触犯独立预备罪与其他犯罪时,应依照处罚较重的规定定罪处罚。%The Criminal Code does not provide a separate offense preparatory legal punishment , but it can be compared to the completed crime to be punished lighter, reduced or waived. When the criminal law provisions take the preparatory acts as separate offenses, the acts at this time are a state of practice rather than a ready status. The implementation of the preparatory acts is defined as an independent preparatory crime. It’s a kind of protection of the legal interests, but it expands the scope of criminal law penalties, and therefore it is necessary to enunciate the clear limitations. The preparatory acts are non-implementation of crime. After the implementation of preparatory acts , tools preparation and other conditions for making the crime become acts of perpetrating which may be attempted , that is the crime of attempted independent preparation. Preparatory acts while committing the crime and other crimes independent preparation, they should be punished in accordance with the provisions for a heavier convicted and punished.

    Buxner, Sanlyn; Holbrook, Jarita

    2016-10-01

    Now in its fourth year, the AAS Oral History Project has interviewed over 100 space scientists from all over the world. Led by the AAS Historical Astronomy Division (HAD) and partially funded by the American Institute of Physics Niels Bohr Library and ongoing support from the AAS, volunteers have collected oral histories from space scientists at professional meetings starting in 2015, including AAS, DPS, and the IAU general assembly. Each interview lasts one and a half to two hours and focuses on interviewees' personal and professional lives. Questions include those about one's family, childhood, strong influences on one's scientific career, career path, successes and challenges, perspectives on how astronomy is changing as a field, and advice to the next generation. Each interview is audio recorded and transcribed, the content of which is checked with each interviewee. Once complete, interview transcripts are posted online as part of a larger oral history library at https://www.aip.org/history-programs/niels-bohr-library/oral-histories. We will present preliminary analysis of those interviewed including characterizing career status, age range, nationality, and primary field. Additionally, we will discuss trends beginning to emerge in analysis of participants' responses about data driven science and advice to the next generation. Future analysis will reveal a rich story of space scientists and will help the community address issues of diversity, controversies, and the changing landscape of science. We are actively recruiting individuals to be interviewed at this meeting from all stages of career from undergraduate students to retired and emeritus astronomers. We are especially interested in interviewing 40+E members of DPS. Contact Sanlyn Buxner to schedule an interview or to find out more information about the project (buxner@psi.edu). Contact Jarita Holbrook if you would like to become an interviewer for the project (astroholbrook@gmail.com).

  1. AA quadrupole magnet

    CERN Multimedia

    1980-01-01

    Focusing magnet used for the AA (antiproton accumulator).Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 - three hundred thousand million - antiprotons. About focusing magnets (quadrupoles): Quadrupole magnets are needed to focus the particle beams and squeeze them so that more particles collide when the beams cross. Particle beams are stored for about 10 hours in the LHC. During this time, the particles make four hundred million revolutions around the machine, travelling a distance equivalent to the diameter of the solar system.

    Full Text Available Researches about child’s intellectual development in the psychology has started in the 19th century and the first step has been made by Tiedemann in “ Observation of the development of the mental abilities of the children”. His work caused a great interest in the circles of doctors and psychologists. Their interpretation of intelligence was different, but the most acceptable is the performance of complicated activities for getting knowledge and skills and getting over the obstacles in the development of the person”.The social ability do not correspond with the intelligence. The two aspects are tested and a complete picture of their functioning can be seen. The developmental principle is determined from general to the separate as functionally connected.In the period when a child does not accept the higher level of intelligence and thinking , in relation to which are effectuated by sense-motor activities, than we say that a child is mentally handicapped. The widest approach of the educational system should be treated as a functional, institutional and organizational, that takes part in the realization of the social aims and tasks.Not getting into viewing of the curriculum's and programs for preparatory groups in the preeducational period, we may say that the justification for the existence of these group in the regular schools, is maturation of the perceptive motor coordination and learning. With the maturing the function of the "ego" is increasing.As a child adapts better he can learn better, and the maturity comes sooner. In this way these groups are justified.Mentally handicapped child has not the opportunity to attend an organized prepared education which provides:-forming of the speech, self-control, which can be achieved in the process of learning through a direct contact with other children;· regulation of the lateralization through re-education of the psycho-motor abilities, and in general neuro-motor experienced maturation

    1995-01-01

    This multiple case study of ten families of normal private preparatory school adolescents and five families of substance abusing/mood disordered adolescents was an effort to identify factors that may suggest a relationship between the abuse of substances in adolescents who also have mood disorders and the following family factors: parental marital discord, degree of family satisfaction, and family problem-solving styles. The fifteen families completed four assessment instruments and participated in a videotaped problem-solving exercise. The results of this study showed that all members of the substance abusing/mood disordered adolescents' families rated themselves as dysfunctional in all major areas of family life. In contrast, the normal private preparatory school families reported satisfaction with most areas of family functioning. Communication styles also differed considerably between the two small groups of families. These results appear to support the importance of family evaluation and treatment when addressing the issue of adolescent substance abusers with mood disorders.

  7. Functional Roles of Neural Preparatory Processes in a Cued Stroop Task Revealed by Linking Electrophysiology with Behavioral Performance.

    Directory of Open Access Journals (Sweden)

    Chao Wang

    Full Text Available It is well established that cuing facilitates behavioral performance and that different aspects of instructional cues evoke specific neural preparatory processes in cued task-switching paradigms. To deduce the functional role of these neural preparatory processes the majority of studies vary aspects of the experimental paradigm and describe how these variations alter markers of neural preparatory processes. Although these studies provide important insights, they also have notable limitations, particularly in terms of understanding the causal or functional relationship of neural markers to cognitive and behavioral processes. In this study, we sought to address these limitations and uncover the functional roles of neural processes by examining how variability in the amplitude of neural preparatory processes predicts behavioral performance to subsequent stimuli. To achieve this objective 16 young adults were recruited to perform a cued Stroop task while their brain activity was measured using high-density electroencephalography. Four temporally overlapping but functionally and topographically distinct cue-triggered event related potentials (ERPs were identified: 1 A left-frontotemporal negativity (250-700 ms that was positively associated with word-reading performance; 2 a midline-frontal negativity (450-800 ms that was positively associated with color-naming and incongruent performance; 3 a left-frontal negativity (450-800 ms that was positively associated with switch trial performance; and 4 a centroparietal positivity (450-800 ms that was positively associated with performance for almost all trial types. These results suggest that at least four dissociable cognitive processes are evoked by instructional cues in the present task, including: 1 domain-specific task facilitation; 2 switch-specific task-set reconfiguration; 3 preparation for response conflict; and 4 proactive attentional control. Examining the relationship between ERPs and behavioral

    Olumide, Funmi; Newton, J Tim; Dunne, Stephen; Gilbert, David B

    2009-09-01

    This study sought to explore whether viewing a leaflet explaining the benefits of dental treatment would have a significant impact on children's anticipatory anxiety. Fifty children aged 8-12, attending the paediatric dental clinic of King's College Hospital, London, took part in this triple-masked, randomized control study. The participants were randomly allocated to one of two groups and either shown an intervention leaflet containing child-friendly dental information (the experimental group) or a leaflet with child-friendly information on the benefits of healthy eating (the control group). Using the Facial Image Scale, anxiety was measured when the children arrived for their dental appointment, once before reading the leaflet and again after reading the leaflet. There was no statistically significant effect of the experimental leaflet on self-reported anxiety levels in this study, although anxiety levels did drop slightly in both groups after reading a leaflet. Providing paediatric patients with preparatory information about what to expect from a visit to the dentist had no effect on anticipatory anxiety in comparison to reading a leaflet about healthy eating. We speculate that reading, or cognitive processing, may have some beneficial effect. Future work should investigate this possibility.

  10. The preparatory set: A novel approach to understanding "stress", trauma, and the bodymind therapies

    2015-04-01

    Full Text Available Basic to all motile life is a differential approach/avoid response to perceived features of environment. The stages of response are initial reflexive noticing and orienting to the stimulus, preparation, and execution of response. Preparation involves a coordination of many aspects of the organism: muscle tone, posture, breathing, autonomic functions, motivational/emotional state, attentional orientation and expectations. The organism organizes itself in relation to the challenge. We propose to call this the preparatory set (PS. We suggest that the concept of the PS can offer a more nuanced and flexible perspective on the stress response than do current theories. We also hypothesize that the mechanisms of bodymind therapeutic and educational systems (BTES can be understood through the PS framework. We suggest that the BTES, including meditative movement, meditation, somatic education, and the body-oriented psychotherapies, are approaches that use interventions on the PS to remedy stress and trauma. We discuss how the PS can be adaptive or maladaptive, how BTES interventions may restore adaptive PS, and how these concepts offer a broader and more flexible view of the phenomena of stress and trauma. We offer supportive evidence for our hypotheses, and suggest directions for future research. We believe that the PS framework will point to ways of improving the management of stress and trauma, and that it will suggest directions of research into the mechanisms of action of BTES.

  11. Electrophysiological evidence for abnormal preparatory states and inhibitory processing in adult ADHD

    2010-10-01

    Full Text Available Abstract Background Attention deficit hyperactivity disorder (ADHD is a common neurodevelopmental disorder that starts in childhood and frequently persists in adults. Several theories postulate deficits in ADHD that have effects across many executive functions or in more narrowly defined aspects, such as response inhibition. Electrophysiological studies on children, however, indicate that ADHD is not associated with a core deficit of response inhibition, as abnormal inhibitory processing is typically preceded or accompanied by other processing deficits. It is not yet known if this pattern of abnormal processing is evident in adult ADHD. Methods The objective of this paper was to investigate event-related potential indices of preparatory states and subsequent response inhibition processing in adults with ADHD. Two cued continuous performance tasks were presented to 21 adults meeting current criteria for adult ADHD and combined type ADHD in childhood, and 20 controls. Results The ADHD group exhibited significantly weaker orienting attention to cues, cognitive preparation processes and inhibitory processing. In addition, we observed a strong correlation between the resources allocated to orienting to cues and the strength of the subsequent response strength control processes, suggesting that orienting deficits partly predict and determine response control deficits in ADHD. Conclusions These findings closely resemble those previously found in children with ADHD, which indicate that there is not a core response inhibition deficit in ADHD. These findings therefore suggest the possibility of developmental stability into adulthood of the underlying abnormal processes in ADHD.

  12. SmartCanvas: Context-inferred Interpretation of Sketches for Preparatory Design Studies

    KAUST Repository

    Zheng, Youyi

    2016-05-27

    In early or preparatory design stages, an architect or designer sketches out rough ideas, not only about the object or structure being considered, but its relation to its spatial context. This is an iterative process, where the sketches are not only the primary means for testing and refining ideas, but also for communicating among a design team and to clients. Hence, sketching is the preferred media for artists and designers during the early stages of design, albeit with a major drawback: sketches are 2D and effects such as view perturbations or object movement are not supported, thereby inhibiting the design process. We present an interactive system that allows for the creation of a 3D abstraction of a designed space, built primarily by sketching in 2D within the context of an anchoring design or photograph. The system is progressive in the sense that the interpretations are refined as the user continues sketching. As a key technical enabler, we reformulate the sketch interpretation process as a selection optimization from a set of context-generated canvas planes in order to retrieve a regular arrangement of planes. We demonstrate our system (available at http:/geometry.cs.ucl.ac.uk/projects/2016/smartcanvas/) with a wide range of sketches and design studies. © 2016 The Author(s) Computer Graphics Forum © 2016 The Eurographics Association and John Wiley & Sons Ltd.

  15. Preparatory Body State before Reacting to an Opponent: Short-Term Joint Torque Fluctuation in Real-Time Competitive Sports.

    Directory of Open Access Journals (Sweden)

    Keisuke Fujii

    Full Text Available In a competitive sport, the outcome of a game is determined by an athlete's relationship with an unpredictable and uncontrolled opponent. We have previously analyzed the preparatory state of ground reaction forces (GRFs dividing non-weighted and weighted states (i.e., vertical GRFs below and above 120% of body weight, respectively in a competitive ballgame task and demonstrated that the non-weighted state prevented delay of the defensive step and promoted successful guarding. However, the associated kinetics of lower extremity joints during a competitive sports task remains unknown. The present study aims to investigate the kinetic characteristics of a real-time competitive sport before movement initiation. As a first kinetic study on a competitive sport, we initially compared the successful defensive kinetics with a relatively stable preparatory state and the choice-reaction sidestep as a control movement. Then, we investigated the kinetic cause of the outcome in a 1-on-1 dribble in terms of the preparatory states according to our previous study. The results demonstrated that in successful defensive motions in the non-weighted state guarding trial, the times required for the generation of hip abduction and three extension torques for the hip, knee, and ankle joints were significantly shortened compared with the choice-reaction sidestep, and hip abduction and hip extension torques were produced almost simultaneously. The sport-specific movement kinetics emerges only in a more-realistic interactive experimental setting. A comparison of the outcomes in the 1-on-1 dribble and preparatory GRF states showed that, in the non-weighted state, the defenders guarded successfully in 68.0% of the trials, and the defender's initiation time was earlier than that in the weighted state (39.1%. In terms of kinetics, the root mean squares of the derivative of hip abduction and three extension torques in the non-weighted state were smaller than those in the

  16. Inefficient preparatory fMRI-BOLD network activations predict working memory dysfunctions in patients with schizophrenia

    Full Text Available Patients with schizophrenia show abnormal dynamics and structure of temporally coherent networks (TCNs assessed using fMRI, which undergo adaptive shifts in preparation for a cognitively demanding task. During working memory (WM tasks, patients with schizophrenia show persistent deficits in TCNs as well as EEG indices of WM. Studying their temporal relationship during WM tasks might provide novel insights into WM performance deficits seen in schizophrenia.Simultaneous EEG-fMRI data were acquired during the performance of a verbal Sternberg WM task with two load levels (load 2 & load 5 in 17 patients with schizophrenia and 17 matched healthy controls. Using covariance mapping, we investigated the relationship of the activity in the TCNs before the memoranda were encoded and EEG spectral power during the retention interval. We assessed four TCNs – default mode network (DMN, dorsal attention network (dAN, left and right working memory networks (WMNs – and three EEG bands – theta, alpha, and beta.In healthy controls, there was a load dependent inverse relation between DMN and frontal-midline theta power and an anti-correlation between DMN and dAN. Both effects were not significantly detectable in patients. In addition, healthy controls showed a left-lateralized load-dependent recruitment of the WMNs. Activation of the WMNs was bilateral in patients, suggesting more resources were recruited for successful performance on the WM task.Our findings support the notion of schizophrenia patients showing deviations in their neurophysiological responses before the retention of relevant information in a verbal WM task. Thus, treatment strategies as neurofeedback targeting pre-states could be beneficial as task performance relies on the preparatory state of the brain.

    2006-04-01

    Full Text Available Abstract Background Gene expression profiling by microarray analysis of cells enriched by laser capture microdissection (LCM faces several technical challenges. Frozen sections yield higher quality RNA than paraffin-imbedded sections, but even with frozen sections, the staining methods used for histological identification of cells of interest could still damage the mRNA in the cells. To study the contribution of staining methods to degradation of results from gene expression profiling of LCM samples, we subjected pellets of the mouse plasma cell tumor cell line TEPC 1165 to direct RNA extraction and to parallel frozen sectioning for LCM and subsequent RNA extraction. We used microarray hybridization analysis to compare gene expression profiles of RNA from cell pellets with gene expression profiles of RNA from frozen sections that had been stained with hematoxylin and eosin (H&E, Nissl Stain (NS, and for immunofluorescence (IF as well as with the plasma cell-revealing methyl green pyronin (MGP stain. All RNAs were amplified with two rounds of T7-based in vitro transcription and analyzed by two-color expression analysis on 10-K cDNA microarrays. Results The MGP-stained samples showed the least introduction of mRNA loss, followed by H&E and immunofluorescence. Nissl staining was significantly more detrimental to gene expression profiles, presumably owing to an aqueous step in which RNA may have been damaged by endogenous or exogenous RNAases. Conclusion RNA damage can occur during the staining steps preparatory to laser capture microdissection, with the consequence of loss of representation of certain genes in microarray hybridization analysis. Inclusion of RNAase inhibitor in aqueous staining solutions appears to be important in protecting RNA from loss of gene transcripts.

    Maeda, Kaoru; Fujiwara, Katsuo

    2007-01-01

    We investigated CNS motor preparation state and anticipatory postural muscle activation while subjects performed bilateral rapid arm movement at various intervals between warning and response stimulus (preparatory period) during standing. Motor preparation state was evaluated by integrated values of the late components of the contingent negative variation (late CNV), obtained by averaging electroencephalograms during the last 100ms of the preparatory period. For quantifying anticipatory postural muscle activation, we measured the onset of burst activity in postural muscles (lumbar paraspinal, biceps femoris, and gastrocnemius) with respect to anterior deltoid activity and integrated values of preceding activation. Subjects performed the arm movement with minimal delay in the warning stimulus-response stimulus-motor response paradigm under preparatory periods of 2.0, 3.0 and 3.5s. Late CNV did not differ between the 2.0-s and 3.0-s period, but was significantly smaller in the 3.5-s period than in the 2.0-s period, suggesting difficulty in predicting response timing in the 3.5-s period. No change was found on integrated values of preceding activations of postural muscles. Burst onset of all postural muscles significantly preceded anterior deltoid activation in all periods. Burst activity for gastrocnemius only occurred earlier in the 3.5-s period than in the 2.0-s and 3.0-s periods. Weak correlations were observed between late CNV and onset time of gastrocnemius activity. It is suggested that earlier activation of gastrocnemius is a strategy adopted when response stimulus timing is relatively difficult to predict.

    2001-03-01

    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a very important treaty, not only for Japan but also for the world, because it prohibits any nuclear weapon test explosion or any other nuclear explosion anywhere in the world. The treaty however will not enter into force until it has been signed and ratified by all the 44 states listed in Annex 2 to the treaty. Many efforts to facilitate the treaty's early entry into force are being done by many countries and many international organizations. As one of result of these efforts, a Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization had be established at a meeting of State Signatories on 19 November 1996, and the Commission started activities to establish global verification regime of the treaty and to prepare for its entry into force. Under the CTBT activities, the Japan Atomic Energy Research Institute (JAERI) is expected to play an important role as supporter for the Japanese Government, especially in a field of an International Monitoring System (IMS). However, there is no appropriate guide book on the CTBT for JAERI staff at present. This report provides some introduction of the CTBT regime and preparatory activities for its entry into force. Only open source information is used for making the report. If anyone need more detail information, it should be asked to contact competent authorities. (author)

    Placebos have been found to affect a number of pathological processes and physiological functions through expectations of clinical improvement. Recently, the study of the placebo effect has moved from the clinical to the physical performance setting, wherein placebos can boost performance by increasing muscle work and by decreasing perceived exertion. However, nothing is known about the neurobiological underpinnings of this phenomenon. Here we show for the first time that a placebo, which subjects believed to be endurance-increasing caffeine, reduces fatigue by acting at the central level on the preparatory phase of movement. In fact, we recorded the readiness potential, which is the expression of the preparatory phase of movement at the level of the supplementary motor area, during repeated flexions of the index finger in a control group that did not receive any treatment and in a placebo group that received placebo caffeine. In the control group, as the number of flexions increased, both fatigue and readiness potential amplitude increased. By contrast, in the placebo group, as the number of flexions increased we found a decrease in perceived exertion along with no increase in readiness potential amplitude. This placebo-induced modulation of the readiness potential suggests that placebos reduce fatigue by acting centrally during the anticipatory phase of movement, thus emphasizing the important role of the central nervous system in the generation of fatigue.

    Numerous studies and clinical anecdotes reveal a relationship between attendance at A.A. meetings and/or degree of involvement in A.A. and maintenance of sobriety. Hypotheses as to how A.A. and/or the A.A. meeting is helpful to its members have ranged from a focus on factors common to all therapy groups, to aspects of A.A. "treatment" which are behavioral in nature. Presented here is another way of understanding A.A.'s effectiveness within the frame of more recent, constructivistic approaches to family therapy. In particular, the A.A. topic meeting is compared to the reflecting team concept of Tom Anderson.

    Full Text Available Introduction: The male-to-female transgender (waria is part of a key population at higher risk for HIV. This study aims to test whether psychosocial determinants as defined by the theory of planned behaviour (TPB can explain behaviours related to condom use among waria. Three preparatory behaviours (getting, carrying, and offering a condom and two condom use behaviours (during receptive and insertive anal sex were assessed. Methods: The study involved 209 waria, recruited from five districts in Jakarta and interviewed by using structured questionnaires. Specific measures were developed to study attitudes, subjective norms and perceived behavioural control (PBC in order to predict intentions and behaviours. Results: The explained variance between intentions with regard to three preparatory behaviours and two condom uses ranged between 30 and 57%, and the variance between the actual preparatory behaviours of three preparatory and two condom uses ranged between 21 and 42%. In our study, as with several previous studies of the TPB on HIV protection behaviours, the TPB variables differed in their predictive power. With regard to intention, attitude and PBC were consistently significant predictors; attitude was the strongest predictor of intention for all three preparatory behaviours, and PBC was the strongest predictor of intention for condom use, both during receptive and insertive anal sex. TPB variables were also significantly related to the second parameter of future behaviour: actual (past behaviour. TPB variables were differentially related to the five behaviours. Attitude was predictive in three behaviours, PBC in three behaviours and subjective norms in two behaviours. Conclusions: Our results have implications for the development of interventions to target preparatory behaviours and condom use behaviours. Five behaviours and three psychological factors as defined in the TPB are to be targeted.

    The American Astronomical Society, in partnership with the Astronomical Society of the Pacific (ASP), has launched a series of professional-development workshops and a community of practice designed to improve early-career astronomers’ ability to communicate effectively with students and the public. Called AAS Astronomy Ambassadors, the program provides training and mentoring for young astronomers, from advanced undergraduates to beginning faculty; it also provides them access to resources and a network of contacts within the astronomy education and public outreach (EPO) community. Ambassadors are provided with a library of outreach activities and resource materials suitable for a range of venues and audiences. For much of this library we are using resources developed by organizations such as the ASP, the Pacific Science Center, and the Center for Astronomy Education for other outreach programs, though some resources have been created by one of us (AF) specifically for this program. After a period of evaluation and revision, the program’s “Menu of Outreach Opportunities for Science Education” (MOOSE) is now posted on the AAS website at http://aas.org/outreach/moose-menu-outreach-opportunities-science-education.The first two Astronomy Ambassadors workshops were held at AAS meetings in January 2013 and January 2014; each served 30 young astronomers chosen from about twice that many applicants. Web-based follow-up activities are being provided through a website at the ASP designed to keep cohorts of educators trained in their programs in touch with one another. The AAS is exploring ways to fund additional workshops at future winter meetings; suggestions are most welcome. Meanwhile, the Astronomy Ambassadors trained to date have logged more than 150 outreach events, reaching many thousands of children and adults across the U.S. and Canada.

    The purpose of the Laboratory Astrophysics Division (LAD) is to advance our understanding of the Universe through the promotion of fundamental theoretical and experimental research into the underlying processes that drive the Cosmos. LAD represents all areas of astrophysics and planetary sciences. The first new AAS Division in more than 30 years, the LAD traces its history back to the recommendation from the scientific community via the White Paper from the 2006 NASA-sponsored Laboratory Astrophysics Workshop. This recommendation was endorsed by the Astronomy and Astrophysics Advisory Committee (AAAC), which advises the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), and the U.S. Department of Energy (DOE) on selected issues within the fields of astronomy and astrophysics that are of mutual interest and concern to the agencies. In January 2007, at the 209th AAS meeting, the AAS Council set up a Steering Committee to formulate Bylaws for a Working Group on Laboratory Astrophysics (WGLA). The AAS Council formally established the WGLA with a five-year mandate in May 2007, at the 210th AAS meeting. From 2008 through 2012, the WGLA annually sponsored Meetings in-a-Meeting at the AAS Summer Meetings. In May 2011, at the 218th AAS meeting, the AAS Council voted to convert the WGLA, at the end of its mandate, into a Division of the AAS and requested draft Bylaws from the Steering Committee. In January 2012, at the 219th AAS Meeting, the AAS Council formally approved the Bylaws and the creation of the LAD. The inaugural gathering and the first business meeting of the LAD were held at the 220th AAS meeting in Anchorage in June 2012. You can learn more about LAD by visiting its website at http://lad.aas.org/ and by subscribing to its mailing list.

    According to the 2007 Ethiopian census, youths aged 15-24 years were more than 15.2 million which contributes to 20.6% of the whole population. These very large and productive groups of the population are exposed to various sexual and reproductive health risks. The aim of this study was to assess exposure to Sexually Explicit Materials (SEM) and factors associated with exposure among preparatory school students in Hawassa city, Southern Ethiopia. A cross-sectional institution based study involving 770 randomly selected youth students of preparatory schools at Hawassa city. Multi stage sampling technique was used to select study subjects. Data was collected using pre-tested and self-administered questionnaire. Data was entered by EPI INFO version 3.5.1 and analyzed using SPSS version 20.0 statistical software packages. The result was displayed using descriptive, bivariate and multivariate analysis. Statistical association was done for independent predictors (at p reproductive health education at their school. Male students had faced almost two times higher exposure to SEM than female students (95 % CI: AOR 1.84(C.I = 1.22, 2.78). Students who attended private school were more than two times more likely exposed to SEM than public schools (95 % CI: AOR 2.07(C.I = 1.29, 3.30). Students who drink alcohol and labelled as 'sometimes' were two times more likely exposed to SEM than those who never drink alcohol (95 % CI = AOR 2.33(C.I = 1.26, 4.30). Khat chewers who labelled "rarely", "sometimes" and "often" had shown higher exposure (95 % CI: AOR 3.02(CI = 1.65, 5.52), (95 % CI: AOR 3.40(CI = 1.93, 6.00) and (95 % CI: AOR 2.67(CI = 1.46, 4.86) than those who never chew khat, respectively. Regarding SEM access, school youths with label 'easy access were exposed in odds of six folds than youths of no access (95 % CI: AOR 5.64(C.I = 3.56, 8.9). High number of students was exposed to sexually explicit materials. Sex, school type, substance use

    2012-01-04

    Social support for abstinence in Alcoholics Anonymous (AA) has been reported to be a consistent factor accounting for AA benefit. However, the nonspecific or unintended effects of such support remain poorly understood and rarely investigated. This prospective study investigated how one nonspecific factor-perceived AA group cohesiveness-predicted increased practice of AA-related behaviors. Findings indicated that impressions of AA group cohesion predicted increased AA attendance, the practice of prescribed AA activities, and self-reported AA usefulness. It appears that a sense of belongingness predicts subsequent engagement in the AA social network that, in turn, is predictive of increased abstinence.

    Conclusion: The inverse relation between insulin and IGFBP-1 was lost during MPET, as these 2 molecules changed in the same direction. The results obtained suggest less severe stress-induced depression of insulin and IGFBP-1 after preparatory training. But another metabolic mechanism cannot be excluded, and that is potentially impaired insulin sensitivity resulting in higher level of IGFBP-1.

    Widespread adoption of empirically-supported treatment innovations has the potential to improve effectiveness of treatment received by individuals with substance use disorders. However, the process of disseminating such innovations has been complex, slow, and difficult. We empirically describe the dissemination and adoption of a treatment innovation--an alcohol-treatment preparatory therapeutic procedure based on motivational interviewing (MI)--in the context of Rogers' (2003) five stages of innovation-decision process (knowledge, persuasion, decision, implementation and confirmation). To this end, 145 randomly-chosen outpatient addiction treatment clinics in New York State received an onsite visit from a project trainer delivering one of three randomly-assigned dissemination intensities: a 15-minute, a half-day or a full-day presentation. Across these clinics, 141 primary administrators and 837 clinicians completed questionnaires assessing aspects of five innovation-decision stages. At each clinic, questionnaire administration occurred immediately pre- and post-dissemination, as well as 1 and 6 months after dissemination. Consistent with Rogers' theory, earlier stages of the innovation-decision process predicted later stages. As hypothesized, dissemination intensity predicted clinicians' post-dissemination knowledge. Clinician baseline characteristics (including gender, pre-dissemination knowledge regarding the MI preparatory technique, education, case load, beliefs regarding the nature of alcohol problems, and beliefs and behavior with regard to therapeutic style) predicted knowledge and persuasion stage variables. One baseline clinic characteristic (i.e., clinic mean beliefs and behavior regarding an MI-consistent therapeutic style) predicted implementation stage variables. Findings suggest that dissemination strategies should accommodate clinician and clinic characteristics.

    Full Text Available Definition of preparatory parameters for sterilization regime of canned "Natural Atlantic Mackerel with Oil" is the aim of current study. PRSC software developed at the department of automation and computer engineering is used for preparatory selection. To determine the parameters of process model, in laboratory autoclave AVK-30M the pre-trial process of sterilization and cooling in water with backpressure of canned "Natural Atlantic Mackerel with Oil" in can N 3 has been performed. Gathering information about the temperature in the autoclave sterilization chamber and the can with product has been carried out using Ellab TrackSense PRO loggers. Due to the obtained information three transfer functions for the product model have been identified: in the least heated area of autoclave, the average heated and the most heated. In PRSC programme temporary temperature dependences in the sterilization chamber have been built using this information. The model of sterilization process of canned "Natural Atlantic Mackerel with Oil" has been received after the pre-trial process. Then in the automatic mode the sterilization regime of canned "Natural Atlantic Mackerel with Oil" has been selected using the value of actual effect close to normative sterilizing effect (5.9 conditional minutes. Furthermore, in this study step-mode sterilization of canned "Natural Atlantic Mackerel with Oil" has been selected. Utilization of step-mode sterilization with the maximum temperature equal to 125 °C in the sterilization chamber allows reduce process duration by 10 %. However, the application of this regime in practice requires additional research. Using the described approach based on the developed mathematical models of the process allows receive optimal step and variable canned food sterilization regimes with high energy efficiency and product quality.

Risa set the stage with an elaborate description of the current accepted facts in the era of precision cosmology including the standard model of concordance cosmology, described by seven parameters and an accepted Lambda-CDM paradigm (with a cosmological constant and cold dark matter). The talk stressed on the fact that all these parameters are understood to a percent order precision, which is a remarkable deviation from the time in 1990s when according to Risa, Alan Guth never thought that any of these numbers could be measured precisely!Risa Wechsler describing our current constraints on what Dark Matter could constitute.Joseph Silk discussing limits on cosmological parameters.The CMB measurements, Big Bang Nucleosynthesis estimates and galaxy clustering statistics all contribute to locking down the description of our universe. She emphasized on the tensions between different probes to measure expansion rate H0 of the universe, and small scale predictions of cold dark matter simulations, but she is hopeful that these shall be resolved eventually. Joe Silk followed this up with his interpretation of trying to understand our place in the universe and placing limits on different parameters and

    Friction stir welding (FSW) has been used for joining AA5083 and AA7B04 alloy sheets with the aim of studying the microstructure and the mechanical properties of dissimilar FSW joints obtained by varying the initial base metal state of AA7B04 alloy. The results show that the initial base metal state has a significant impact on the material flow during dissimilar FSW. As compared with the joints placing hard alloy (artificially aged AA7B04-AA or naturally aged AA7B04-NA) on the retreating side, it becomes easier transporting AA5083 from advancing side to retreating side when soft alloy (annealed AA7B04-O) is placed on the retreating side. The atomic diffusion does not occur at the interface between AA5083 and AA7B04, indicating that the mixing of the two materials is merely mechanical. Grain refinement is observed in the stir zone. The failure location during tensile tests is different depending on the initial base metal state. The joints (AA5083/AA7B04-AA and AA5083/AA7B04-O) fail in the base metal on the soft material side which corresponds to the minimum values in hardness profiles. Differently, the joints (AA5083/AA5083 and AA5083/AA7B04-O) fail in the stir zone due to the presence of defects including "zigzag line," kissing bond and discontinuous voids.

    Electrostatic pickups around the circumference of the AA served for the measurement of the closed orbits across the wide momentum range of +- 3% to either side of central orbit. The pickups were of the "shoebox" type, with diagonal cuts, a horizontal and a vertical one mechanically coupled together. They were located where they would not require extra space. The wide ones (very wide indeed: 70 cm), like the one we see here, were placed inside the vacuum chamber of the wide quadrupoles QFW, at maximum dispersion. See also 8001372, 8001383, 8010045

    Electrostatic pickups around the circumference of the AA served for the measurement of the closed orbits across the wide momentum range of +- 3% to either side of central orbit. The pickups were of the "shoebox" type, with diagonal cuts, a horizontal and a vertical one mechanically coupled together. They were located where they would not require extra space. The wide ones (very wide indeed: 70 cm), like the one we see here, were placed inside the vacuum chamber of the wide quadrupoles, QFW, at maximum dispersion. See also 8001372,8001383, 8010042

    Preparatory training for new trainees beginning residency has been used by a variety of programs across the country. To improve the clinical orientation process for our new postgraduate year (PGY)-1 residents, we developed an intensive preparatory training curriculum inclusive of cognitive and procedural skills, training activities considered essential for early PGY-1 clinical management. We define our surgical PGY-1 Boot Camp as preparatory simulation-based training implemented at the onset of internship for introduction of skills necessary for basic surgical patient problem assessment and management. This orientation process includes exposure to simulated patient care encounters and technical skills training essential to new resident education. We report educational results of 4 successive years of Boot Camp training. Results were analyzed to determine if performance evidenced at onset of training was predictive of later educational outcomes. Learners were PGY-1 residents, in both categorical and preliminary positions, at our medium-sized surgical residency program. Over a 4-year period, from July 2007 to July 2010, all 30 PGY-1 residents starting surgical residency at our institution underwent specific preparatory didactic and skills training over a 9-week period. This consisted of mandatory weekly 1-hour and 3-hour sessions in the Simulation Center, representing a 4-fold increase in time in simulation laboratory training compared with the remainder of the year. Training occurred in 8 procedural skills areas (instrument use, knot-tying, suturing, laparoscopic skills, airway management, cardiopulmonary resuscitation, central venous catheter, and chest tube insertion) and in simulated patient care (shock, surgical emergencies, and respiratory, cardiac, and trauma management) using a variety of high- and low-tech simulation platforms. Faculty and senior residents served as instructors. All educational activities were structured to include preparatory materials

If you said Wikipedia, youre not alone. For many people, Wikipedia is the primary source of information about astronomy and science. However, many Wikipedia articles about science topics are incomplete or missing, and women are underrepresented among scientists with biographies.To address this, the AAS Astronomy Education Board teamed up with the Wiki Education Foundation to host an edit-a-thon as part of the Wikipedia Year of Science. More than forty attendees spent the better part of three hours working through tutorials, creating new articles, and editing existing ones. The session was generously sponsored by the Simons Foundation.The Year of Science initiative seeks to bring Wikipedia editing skills to the classroom and help new editors find sustainable ways to contribute to Wikipedia in the long term. Anybody can create a free account and start editing!As a first-time Wikipedia contributor, I took the time to go through nearly all the tutorial exercises and familiarize myself with the process of editing a page. I decided to flesh out one section in an existing page about asteroseismology. Others created biography pages from scratch or selected various astronomical topics to write about. To me, the editing process felt like a cross between writing a blog post and a journal article, in a hack day type environment. Working through the tutorial and some examples renewed my empathy for learners who are tackling a new skill set for the first time. A full summary of our

  12. The cognitive roles of behavioral variability: idiosyncratic acts as the foundation of identity and as transitional, preparatory, and confirmatory phases.

    Science.gov (United States)

    Eilam, David

    2015-02-01

    Behavior in obsessive compulsive disorder (OCD), in habitual daily tasks, and in sport and cultural rituals is deconstructed into elemental acts and categorized into common acts, performed by all individuals completing a similar task, and idiosyncratic acts, not performed by all individuals. Never skipped, common acts establish the pragmatic part of motor tasks. Repetitive performance of a few common acts renders rituals a rigid form, whereby common acts may serve as memes for cultural transmission. While idiosyncratic acts are not pragmatically necessary for task completion, they fulfill important cognitive roles. They form a long preparatory phase in tasks that involve high stakes, and a long confirmatory phase in OCD rituals. Idiosyncratic acts also form transitional phases between motor tasks, and are involved in establishing identity and preserving the flexibility necessary for adapting to varying circumstances. Behavioral variability, as manifested in idiosyncrasy, thus does not seem to be a noise or by-product of motor activity, but an essential cognitive component that has been preserved in the evolution of behavioral patterns, similar to the genetic variability in biology.

    The friction stir weldabilities of the strain-hardened AA1050-H24 and precipitate-hardened AA6061-T6 aluminum alloys were examined to reveal the effects of material properties on the friction stir welding behavior. The experimental results are obtlained. (1) For AA1050-H24, the weld can possess smoother surface ripples; there is no elliptical weld nugget in the weld; there is no discernible interface between the stir zone and the thermomechanically affected zone;and the internal defect of the weld looks like a long crack and is located in the lower part of the weld. (2) For AA6061-T6, the weld usually possesses slightly rougher surface ripples; an elliptical weld nugget clearly exists in the weld; there are discernible interfaces among the weld nugget, thermomechanically affected zone and heat affected zone; and the internal defect of the weld is similar to that of the AA1050-H24 weld. (3) The effective range of welding parameters for AA1050-H24 is narrow, while the one for AA6061-T6 is very wide. (4) The maximum tensile strength efficiency of the AA1050-H24 joints is similar to that of the AA6061-T6 joints, i.e. 79% and 77%, respectively.

    This article starts by discussing the potential disadvantages of traditional assessment towards young English as a Second Language (ESL) learners within the American public school education system. In response to such disadvantages, researchers ’call for the implementation of alternative assessments (AAs) is therefore introduced along with the various benefits of AAs. However, the current mainstream education policy in the US, namely No Child Left Behind (NCLB) Policy, is still largely based on the tra-ditional ways of testing, making policy-oriented implementation of AAs on large scales remarkably difficult. After careful analysis, the author points out several implications concerning how, under such an existing policy of NCLB, can practitioners effectively accommodate young ESL learners by applying the power of AAs.

    Full Text Available BACKGROUND: Reaching the highest levels of performance in top-level sport relates to an assumption of optimal development of somatic parameters that form an important part of the sport performance. OBJECTIVE: The aim of this study is to capture the dynamics of the morphological changes and performance parameters of the current Czech junior representatives in whitewater slalom with regard to a five-month preparatory period. METHODS: The survey was carried out at the beginning of the preparatory period and after its termination (5 months. 21 representatives of the Czech Republic from the Junior Slalom category on whitewater participated in this research. Of the total studied probands were 14 men with a mean age of 16.03 ±0.56 years. There were 7 women with a mean age of 16.20 ±1.12 years. The anthropometric methods and bioelectrical impedance method (BIA were used. Performance indicators evaluated the development of muscle power capabilities of the upper extremities, abdominal muscle development and aerobic ability. The research data was processed by the appropriate procedures in the program Antrop vers. 2000.1. Statistical analysis was performed in Statistica vers.10.0. RESULTS: Changes in morphological parameters with respect to a fivemonth preparatory period are reflected especially at the level of body composition and individual fractions. In a group of male and female athletes in slalom there was a reduction in the absolute values of body fat with simultaneous increase in muscle fraction and the total increase in lean body mass. In both groups there was an overall segmental reduction in the percentage of body fat, however changes are not significant. Changes in somatotype with regard to a five-month preparatory period are insignificant in both groups. Changes in selected performance parameters typically show a significant and positive difference in both monitored groups. CONCLUSION: The observed changes of morphological and performance

  2. Reflexive and preparatory selection and suppression of salient information in the right and left posterior parietal cortex.

    2009-06-01

    Attentional cues can trigger activity in the parietal cortex in anticipation of visual displays, and this activity may, in turn, induce changes in other areas of the visual cortex, hence, implementing attentional selection. In a recent TMS study [Mevorach, C., Humphreys, G. W., & Shalev, L. Opposite biases in salience-based selection for the left and right posterior parietal cortex. Nature Neuroscience, 9, 740-742, 2006b], it was shown that the posterior parietal cortex (PPC) can utilize the relative saliency (a nonspatial property) of a target and a distractor to bias visual selection. Furthermore, selection was lateralized so that the right PPC is engaged when salient information must be selected and the left PPC when the salient information must be ignored. However, it is not clear how the PPC implements these complementary forms of selection. Here we used on-line triple-pulse TMS over the right or left PPC prior to or after the onset of global/local displays. When delivered after the onset of the display, TMS to the right PPC disrupted the selection of the more salient aspect of the hierarchical letter. In contrast, left PPC TMS delivered prior to the onset of the stimulus disrupted responses to the lower saliency stimulus. These findings suggest that selection and suppression of saliency, rather than being "two sides of the same coin," are fundamentally different processes. Selection of saliency seems to operate reflexively, whereas suppression of saliency relies on a preparatory phase that "sets up" the system in order to effectively ignore saliency.

This talk featured a broad range of research efforts on exoplanets, with the main focus on how we study the composition of their atmospheres, and how multi-body interactions carve the structure of the planetary systems we observe.One of her first points is the well-known idea that the Solar System is an oddball, compared to the exoplanet systems we have found so far: most of these systems contain hot Jupiters and mini-Neptunes at very close-in orbits around their host stars. Moreover, even when studying their transmission spectra, it is difficult to know the exact composition of their atmospheres.Knutson: it is difficult to constrain atmospheric composition of exoplanets (H-poor or H-rich+clouds?) #aas228pic.twitter.com/LdyN4o9RC7 astrobites (@astrobites) June 15, 2016The main proposal on how these systems formed is the migration scenario. In order to validate this idea, Dr. Knutson and her group The Friends of Hot Jupiters study systems with close-in gas giants and their frequency of binary companions, which are supposed to be the main culprits causing gas-giant migration. They found that approximately half of the observed systems have long-distance companions, providing strong validation of the migration scenario. Moreover, Dr. Knutson speculates that wide binaries have more

  5. Negative Affect, Relapse, and Alcoholics Anonymous (AA): Does AA Work by Reducing Anger?*

    Objective: Anger and other indices of negative affect have been implicated in a stress-induced pathway to relapse. The Alcoholics Anonymous (AA) literature states that reduction of anger is critical to recovery, yet this proposed mechanism has rarely been investigated. Using lagged, controlled hierarchical linear modeling analyses, this study investigated whether AA attendance mobilized changes in anger and whether such changes explained AA-related benefit. Method: Alcohol-dependent adults (N = 1,706) receiving treatment as part of a clinical trial were assessed at intake and at 3, 6, 9, 12, and 15 months. Results: Findings revealed substantially elevated levels of anger compared with the general population (98th percentile) that decreased over 15-month follow-up but remained high (89th percentile). AA attendance was associated with better drinking outcomes, and higher levels of anger were associated with heavier drinking. However, AA attendance was unrelated to changes in anger. Conclusions: Although support was not found for anger as a mediator, there was strong convergence between AA's explicit emphasis on anger and the present findings: Anger appears to be a serious, enduring problem related to relapse and heavy alcohol consumption. Methodological factors may have contributed to the lack of association between AA and anger, but results suggest that AA attendance alone may be insufficient to alleviate the suffering and alcohol-related risks specifically associated with anger.

    Better knowledge is needed about the effectiveness of preparatory English language courses for the health professions. This study evaluated the scientific writing skills of students finishing their preparatory year of a bachelor of dentistry programme in Saudi Arabia. A cross-sectional study was conducted in 2014-15 among first-year dental students at the University of Dammam. Students were asked to write a 150-word English language assignment that was analysed for writing statistics and problems using Microsoft Word and plagiarism detection software. Of the 89 respondents, female students used a significantly greater number of words than did male students and their assignments had significantly lower Flesch reading ease scores. Male students had significantly lower odds of using references (OR 0.04) and higher odds of making punctuation and grammar mistakes (OR 2.63 and 3.91 respectively). One course of scientific writing in the preparatory year may not be enough to develop adequate writing skills among undergraduate dental students.

    The objective of this study was to discover the utility, barriers, and experiences with the use of Alcoholics Anonymous (AA) as a learning resource in the medical school curriculum. A third-year medical student cohort and a psychiatric educator group were queried about learned experiential lessons, attendance requirements, attitudes, and obstacles encountered. Forty-three educators, whose familiarity with AA varied widely, responded to the survey. Forty-seven percent required AA attendance and reported it was a positive experience for their students. Eighty-four percent felt students should attend AA and identified obstacles to its implementation. Separately, descriptive impressions of students (N = 95) who attended AA meetings were collected. Their responses were positive 46%, neutral 43%, or negative 11%. Respondents found AA meeting experiences generally positive, and although impediments to implementation of this experience still exist, they may be overcome with concerted efforts of psychiatric educators.

  9. The AA disappearing under concrete shielding

    1982-01-01

    When the AA started up in July 1980, the machine stood freely in its hall, providing visitors with a view through the large window in the AA Control Room. The target area, in which the high-intensity 26 GeV/c proton beam from the PS hit the production target, was heavily shielded, not only towards the outside but also towards the AA-Hall. However, electrons and pions emanating from the target with the same momentum as the antiprotons, but much more numerous, accompanied these through the injection line into the AA ring. The pions decayed with a half-time corresponding to approximately a revolution period (540 ns), whereas the electrons lost energy through synchrotron radiation and ended up on the vacuum chamber wall. Electrons and pions produced the dominant component of the radiation level in the hall and the control room. With operation times far exceeding original expectations, the AA had to be buried under concrete shielding in order to reduce the radiation level by an order of magnitude.

    On-Site Inspection (OSI) Workshop-5 met 8-12 November, 1999 in Farnborough, UK and was hosted by the Defence Evaluation and Research Agency (DERA). The purpose of the workshop was to provide guidance on OSI Operational Manual (OM) development for Working Group B (WGB) of the CTBT Preparatory Commission (PrepCom). The two main topics of the workshop involved logistics/preparatory activities for the pre-inspection phase and in-depth examination of technology application during the initial and continuation phases of an OSI. Reports from the PTS-sponsored Kazakhstan OSI experiment set the tone for the discussions of logistics and preparatory activities. The most important recommendation coming out of the experiment and workshop discussions is a need for Working Group A to develop specific administrative and financial rules regarding OSIs and define the status of inspectors and inspector assistants with respect to the CTBTO. There was also extensive discussion of a need for Working Group B to develop and/or adapt safety standards. With respect to OSI preparations, the group agreed that the time line and quick response required by an OSI necessitate development of special procedures; standing arrangements and/or advanced parties are suggested as one possible approach and a list of relevant issues has been initiated. A chart was developed that outlines the various elements of logistics required for an OSI that can serve as a basis for development of checklists, databases, and other preparation activities. Technology presentations and discussion focused on three major areas: phenomenology, synergy, and specifications.

    Nurses consistently report the highest levels of job stress among all health professionals. To best prepare students for such a high-stress profession, insights into the onset of stress is warranted, especially with the literature supporting that nursing students experience significant stress during their education. This study sought to explore the sources of stress among nursing students and to compare stress levels and selected mental health indicators between nursing students and the general student body using the paper-and-pencil version of the National College Health Assessment II. Nursing students were found to have significantly more stress, anxiety, sleep disturbances, and stress-related illnesses than the general student body. The findings highlight the importance of self-care and stress management skills education in nurse preparatory programs for use in both academic preparation and in future careers.

It is a huge zoo with about a quarter million zookeepers, they are citizen astronomers who collaboratively classify galaxies by their looks as an attempt to understand galaxy evolution. The big question that is being answered is: how do blue, actively star-forming galaxies evolve into red, quiescent (non-star-forming) galaxies? The Zoo helped reveal that blue galaxies turn into red galaxies via two possible paths galaxies might run out of supply of gas and shut off star formation slowly; or they could merge with one another and turn off star formation by destroying the gas reservoir rapidly!The Galaxy Zoo project also led to the discoveries of:Green Peas: they are the living fossils of galaxy evolution; compact, bright, green galaxies that are actively forming starsOverlapping galaxies: they are pairs of galaxies that are separated physically but happen to lie on the same line of sight; they provide excellent laboratories for studying dust extinctionHannys Voorwerp: an unusual object named after Hanny the discoverer, which is believed to be the first detection of quasar light echoThe idea of Galaxy Zoo in getting help from citizen scientists was further extended into an award-winningproject known as the Zooniverse, which is an online platform for streamlined crowd-sourcing for scientific research that requires human input.

    Vegetative insecticidal proteins (Vips) secreted by some isolates of Bacillus thuringiensis show activity against insects and are regarded as insecticides against pests. A number of B. thuringiensis strains harbouring vip3A genes were isolated from different sources and identified by using a PCR based approach. The isolates with the highest insecticidal activity were indicated in screening tests, and their vip genes were cloned and sequenced. The analysis revealed two polymorphic Vip protein forms, which were classified as Vip3Aa58 and Vip3Aa59. After expression of the vip genes, the proteins were isolated and characterized. The activity of both toxins was estimated against economically important lepidopteran pests of woodlands (Dendrolimus pini), orchards (Cydia pomonella) and field crops (Spodoptera exigua). Vip3Aa58 and Vip3Aa59 were highly toxic and their potency surpassed those of many Cry proteins used in commercial bioinsecticides. Vip3Aa59 revealed similar larvicidal activity as Vip3Aa58 against S. exigua and C. pomonella. Despite 98% similarity of amino acid sequences of both proteins, Vip3Aa59 was significantly more active against D. pini. Additionally the effect of proteolytic activation of Vip58Aa and Vip3Aa59 on toxicity of D. pini and S. exigua was studied. Both Vip3Aa proteins did not show any activity against Tenebrio molitor (Coleoptera) larvae. The results suggest that the Vip3Aa58 and Vip3Aa59 toxins might be useful for controlling populations of insect pests of crops and forests.

    Full Text Available Introduction: Competency-based education has been recommended in training and education of public health to reduce the gap between traditional teaching and the competencies required in practice. Epidemiology as a fundamental of public health science has come to attention. The aim of this study was to introduce a complementary core competency program for Master of Science (MSc in epidemiology students in Iran. Methods: A workgroup in the department of statistics and epidemiology of Tabriz University of Medical Sciences including five epidemiologists and three biostatisticians prepared an outline of complementary core competencies for epidemiology MSc students. In the first step several discussion rounds were done to review the current curriculum, then the workgroup sought students’ opinions to find out about their needs. In addition, a review of the current literature around the topic was done. In the final step the program components were developed by the workgroup and initially implemented. Results: A complementary program consists of eight domains: general knowledge, problem finding, data analysis and interpretation, communications, management, consultation, leadership skills and professionalism. This program focused on basic competencies and those competencies outside the major field for a graduate of epidemiology to enhance their knowledge, attitude and skills. The program was scheduled to run in the third semester and approximate time for completion was three months. Conclusion: The development and initial implementation of the complementary core competency program was successful and the authors will attempt to extend the program and evaluate the implementation phase.

    The present paper discusses the optimization of dissimilar friction stir welding of AA 2219 and AA 7039 alloys with respect to tool design issues including microstructural study of weld. The optimized ultimate tensile strength was ~280 MPa, and % elongation was ~11.5. It was observed that the extent of tool shoulder flat surface and tool rotational speed influenced the weld quality significantly. A mathematical model was also developed using response surface regression analysis to predict the effects of tool geometry and process variables on dissimilar AA 2219 and AA 7039 alloys welds. The microstructure evolution and mechanical properties were investigated by employing electron backscatter diffraction technique, Vickers microhardness, and tensile testing, respectively. The microstructural observations indicated that the grain size obtained at advancing side (AA 2219 alloy side) was much finer compared to the retreating side (AA 7039 alloy side). Hardness distribution in the stir zone was inhomogeneous, which might be due to inadequate mixing of weld zone material. The hardness values observed at the weld zone were lower than that in the base materials.

    Microstructure and material flow of aluminum alloys have a significant influence on the mechanical properties and surface quality. In extrusion of aluminum billets at high temperatures the microstructure is dependent on the alloy and the forming and temperature history. A prediction of grain size and precipitation is of increasing importance in order to design the process by adjustment of parameters such as punch speed, temperatures, and quenching. To give references for microstructure prediction based on material flow, and with it strain and strain rate history, this paper deals with the microstructure during the extrusion process of AA6060, AA6082, and AA7075 alloys. Billets have been partly extruded to axisymmetric round profiles and the microstructure of the press rests consisting of the billet rests in container and die has been considered. Furthermore, these rests have been analyzed to show the material flow, dynamic and static recrystallization based on macro etchings and visible microstructure under different conditions, e.g. as in the area of high strain rate near the container wall, or in dead zones. To allow an accurate simulation of the extrusion process, punch force and temperature conditions during the tests have been measured and are presented in this paper, too.

    and corporal resources used during classes. METHODS: Forty male teachers from a preparatory school were selected for this study. They were assessed in their workplace using two questionnaires. The first questionnaire regarded the workplace and vocal self-evaluation, and the second concerned visual and auditory-perceptual assessment of corporal parameters. The visual and auditory-perceptual assessment was carried out by the examiner during regular 60-minute classes. The parameters analyzed were divided into voice and speech aspects. The parameters that regarded corporal resources analysis were scored on an analogical scale graduated from 0 to 10, where the far left (0 referred to inadequacy, and the far right (10, to complete adequacy. RESULTS: Most teachers (77.5% used microphone during classes and reported vocal signs and symptoms, among which the most cited were: voice failures, hoarseness, speech effort, throat dryness and accumulation of mucus in the throat. Auditory-perceptual analysis showed that teachers had slightly altered vocal quality, being 35% characterized as hoarse. Speech and corporal resources were used adequately most of the time. CONCLUSION: Prep-school teachers showed high incidence of vocal symptoms even when using microphone. They used of several corporal resources in order to enhance learning, and use of gestures, directed eye contact, and verbal interaction with students were the most used strategies during classes.

    The American Astronomical Society, partnering with organizations active in science education and public outreach (EPO), has launched a series of professional-development workshops and a community of practice designed to help improve early-career astronomers’ ability to effectively communicate with students and the public. Called Astronomy Ambassadors, the program provides mentoring and training experiences for young astronomers, from advanced undergraduates to beginning faculty; it also provides access to resources and a network of contacts within the astronomy EPO community. By learning how to implement effective education and outreach strategies, Astronomy Ambassadors become better teachers, better presenters at meetings, and better representatives of our science to the public and to government. And because young astronomers are a more diverse group than those who currently do the majority of outreach, they help the astronomical community present a more multicultural and gender-balanced face to the public, enabling members of underserved groups to see themselves as scientists. Ambassadors are provided with a large library of outreach activities and materials that are suitable for a range of venues and audiences and that will grow with time. For much of this library we are using resources developed by organizations such as the Astronomical Society of the Pacific, the Pacific Science Center, and the Center for Astronomy Education for other outreach programs, though some resources have been created by one of us (AF) specifically for this program. The first Astronomy Ambassadors workshop was held at the 221st meeting of the AAS in January 2013 and served 30 young astronomers chosen from more than 75 applicants. Incorporating feedback from workshop participants and lessons learned from the reports they’ve submitted after conducting their own outreach events, we are now planning the second annual workshop to be held 4-5 January 2014 at the 223rd AAS meeting in

    We present the case of a 45-year-old woman, with two-year history of chronic renal insufficiency and proteinuria. A kidney biopsy showed the presence of AA amyloidosis (positive Congo red staining and immunohistochemistry). There was no evidence of amyloid deposits in other organs and there was no underlying disease. AA amyloidosis normally is secondary to chronic inflammatory or infectious diseases. High levels of IL-1, IL-6 and TNF-α play a role in the pathogenesis of amyloidosis and induce the synthesis of serum amyloid A protein (SAA), a precursor of tissue amyloid deposits. We empirically treated the patient with a low dose colchicine. The patient responded well. Colchicine has been used for the treatment of Familiar Mediterranean Fever and related auto-inflammatory diseases. To monitor treatment responses, we measured SAA finding low titers. Soon after treatment onset there were signs of improvement pertaining to proteinuria and stabilization of renal function.

    AA-stacked graphite shows strong anisotropy in geometric structures and velocity matrix elements. However, the absorption spectra are isotropic for the polarization vector on the graphene plane. The spectra exhibit one prominent plateau at middle energy and one shoulder structure at lower energy. These structures directly reflect the unique geometric and band structures and provide sufficient information for experimental fitting of the intralayer and interlayer atomic interactions. On the other hand, monolayer graphene shows a sharp absorption peak but no shoulder structure; AA-stacked bilayer graphene has two absorption peaks at middle energy and abruptly vanishes at lower energy. Furthermore, the isotropic features are expected to exist in other graphene-related systems. The calculated results and the predicted atomic interactions could be verified by optical measurements.

    People with non-specific low back pain (LBP) show hampered performance of dynamic tasks such as sit-to-stance-to-sit movement. However, the underlying mechanisms remain obscure. Therefore, the aim of this study was to assess if proprioceptive impairments influence the performance of the sit-to-stance-to-sit movement. First, the proprioceptive steering of 20 healthy subjects and 106 persons with mild LBP was identified during standing using muscle vibration. Second, five sit-to-stance-to-sit repetitions on a stable support and on foam were performed as fast as possible. Total duration, phase duration, center of pressure (COP) displacement, pelvic and thoracic kinematics were analyzed. People with LBP used less lumbar proprioceptive afference for postural control compared to healthy people (P pelvic rotation initiation were recorded to start both movement sequences (P pelvic preparatory movement in the LBP group.

    The present work aims to compare two processes: Accumulative Roll Bonding and Cross Accumulative Roll Bonding (CARB). Both processes consist in the repetition of rolling but the second technique adds a 90° rotation of the sheet around its normal direction between each rolling. Microstructure, mechanical properties and texture were compared for both processes on an AA5754/AA6061 composite. As a result a thinner and less elongated microstructure was obtained in the CARB process leading to an isotropy and an improvement of the mechanical properties. Besides, the texture was characterized by the rotated Cube component for both processes but for CARB it is of less strength.

    This paper describes medical students' views of alcoholism and their response to attending an Alcoholics Anonymous (AA) meeting during their psychiatry clerkship. This may assist other educators in planning their addiction curricula. Medical students were required to attend an AA meeting during their psychiatry clerkship and then to write a reflection piece on this experience. We selected a random sample of 40 pieces and performed a qualitative analysis to identify the prominent ideas and themes in this sample. Medical students found their experience attending an AA meeting to be educationally valuable. They reported their familiarity with AA prior to this experience was largely limited to popular media depictions. Students reported understanding alcoholism as a disease with both biological and psychosocial components. They were often concerned with the presence of religiosity and spirituality at the meetings. Following the experience, students felt more comfortable referring patients to AA and identified empathy, honesty, and openness as crucial contributors to the efficacy of AA. Students felt that attending an AA meeting during their psychiatry clerkship was an educationally valuable experience. Medical students' familiarity with addiction treatment is limited, and attending an AA meeting may be helpful in increasing their comfort with treating addicted patients in the future. In addition, educators may want to explicitly address the spirituality issue related to some treatment programs to increase the likelihood that future physicians feel comfortable referring their patients to recovery programs.

  5. AAS Special Session: Policy Making in Astronomy

    1995-12-01

    The professional astronomical community today is more diverse than at any time in its history. Individuals participating in creative research programs can be found in a wide range of positions. This type of diversity, which mixes research, education, and service (e.g. contract) work, represents the strength of contemporary astronomy. While recognizing the unavoidable reductions in funding and restructuring of organizations like NASA, it is imperative that the significance of the current diversity be considered during these processes. Creative ideas are one of the cornerstones of quality research, and they can originate anywhere. Consequently, it is essential that adequate research resources remain available for free and open competition by all astronomers. Our goal in this session is to bring together officials from the AAS, NASA, and the NSF to discuss how the policy and decision making process operates and whether it should be changed to better serve the general needs of the professional astronomical community. Examples of the issues we believe are important include: In establishing new policy, how can the needs of the average research astronomer be better addressed? How could input from such astronomers be provided to those who craft NASA/NSF policy? How can/should the AAS serve as an interface between policy/decision making bodies and its membership? Should the AAS membership become more actively/effectively involved in the decision making process and, if so, how?

    Antiprotons emerging at large angles from the production target (hit by an intense 26 GeV proton beam from the PS), were focused into the acceptance of the injection line of the AA by means of a "magnetic horn" (current-sheet lens). Here we see an early protype of the horn's inner conductor, machined from solid aluminium to a thickness of less than 1 mm. The 1st version had to withstand pulses of 150 kA, 15 us long, every 2.4 s.

The atlas is a result of averaging of spectra recorded with the aid of the echelle spectrograph BOES fed by the 1.8-m telescope at Bohyunsan observatory (Korea). The atlas is provided only in machine-readable form (electronic data file) and will be available in the SIMBAD database upon publication.

  9. Wooden Model of Wide AA Bending Magnet

    CERN Multimedia

    1978-01-01

    The very particular lattice of the AA required 2 types of dipoles (bending magnets: BLG, long and narrow; BST, short and wide). A wide one had a steel length of 2.71 m, a "good field" width of 0.564 m, and a weight of about 75 t. A wooden model was build in 1978, to gain dimensional experience. Here, Peter Zettwoch, one of the largest men at CERN at that time, is putting a hand in the mouth of the wooden BST monster.

    The cytochrome P450 (CYP) 2 gene family is the largest and most diverse CYP gene family in vertebrates. In zebrafish, we have identified 10 genes in a new subfamily, CYP2AA, which does not show orthology to any human or other mammalian CYP genes. Here we report evolutionary and structural relationships of the 10 CYP2AA genes and expression of the first two genes, CYP2AA1 and CYP2AA2. Parsimony reconstruction of the tandem duplication pattern for the CYP2AA cluster suggests that CYP2AA1, CYP2AA2 and CYP2AA3 likely arose in the earlier duplication events and thus are most diverged in function from the other CYP2AAs. On the other hand, CYP2AA8 and CYP2AA9 are genes that arose in the latest duplication event, implying functional similarity between these two CYPs. A molecular model of CYP2AA1 showing the sequence conservation across the CYP2AA cluster reveals that the regions with the highest variability within the cluster map onto CYP2AA1 near the substrate access channels, suggesting differing substrate specificities. Zebrafish CYP2AA1 transcript was expressed predominantly in the intestine, while CYP2AA2 was most highly expressed in the kidney, suggesting differing roles in physiology. In the liver CYP2AA2 expression but not that of CYP2AA1, was increased by 1,4-bis [2-(3,5-dichloropyridyloxy)] benzene (TCPOBOP) and, to a lesser extent, by phenobarbital (PB). In contrast, pregnenolone 16α-carbonitrile (PCN) increased CYP2AA1 expression, but not CYP2AA2 in the liver. The results identify a CYP2 subfamily in zebrafish that includes genes apparently induced by PB-type chemicals and PXR agonists, the first concrete in vivo evidence for a PB-type response in fish. - Highlights: • A tandemly duplicated cluster of ten CYP2AA genes was described in zebrafish. • Parsimony and duplication analyses suggest pathways to CYP2AA diversity. • Homology models reveal amino acid positions possibly related to functional diversity. • The CYP2AA locus does not share synteny with

    To investigate students' reasons for choosing general or paediatric nursing, and to compare motivation factors and personal characteristics between the two professions. In Italy, nursing students can choose between two distinct career paths: general and paediatric nursing. However, it is unclear what factors motivate a student to choose between these two pathways. A cross-sectional approach was used to compare a sample of general and paediatric nursing students enrolled in a university in northeast Italy. We administered a questionnaire that covered socio-demographic characteristics and included an instrument of motivation developed by Zysberg & Berry to 224 students enrolled in the 3-year classes. We analysed 215 questionnaires (96%). Paediatric nurses were generally younger, had attended a college preparatory high school and had previously failed another university programme. Many students, in both groups, had a relative who was a nurse, or had cared for a sick friend or family member. Students did not vary significantly in how they evaluated items included in the questionnaire. A career in nursing should be advised for students who are motivated to help other people. Paediatric nursing was identified as an acceptable career choice by students of college preparatory high schools or by students who had initially enrolled in a different university programme. General nursing was a satisfactory choice by students with previous work experience. © 2012 The Authors. International Nursing Review © 2012 International Council of Nurses.

    Craciun, Catrinel; Flick, Uwe

    2015-12-01

    Preparing for positive aging is shaped by the social context a person lives in. The present qualitative study explores and compares representations about preparatory actions in precarious workers (i.e., with temporary job contracts and insecure pension plans) and individuals with secure pension plans living in Germany. It also examines, the discrepancy between what middle-aged persons think they should be doing in preparation and what they report doing for aging well. Findings from the analysis of the semi-structured interviews conducted here show that people who have insecure pension plans tend to see themselves as social networkers and optimists, while those with secure pension plans see themselves as social activists and careful planners of old age. All participants value an active, healthy body but manage to do little in order to attain it due to lacking time and discipline. In accordance with the socioemotional selectivity theory, perceiving a short-time perspective makes precarious individuals focus on emotional goals, while financially secure individuals value social goals. Implications for practice and policy change are discussed.

    2008-10-01

    Cry4Aa produced by Bacillus thuringiensis is a dipteran-specific toxin and is, therefore, of great interest for developing a bioinsecticide to control mosquitoes. However, the expression of Cry4Aa in Escherichia coli is relatively low, which is a major disadvantage in its development as a bioinsecticide. In this study, to establish an effective production system, a 1,914-bp modified gene (cry4Aa-S1) encoding Cry4Aa was designed and synthesized in accordance with the G + C content and codon preference of E. coli genes without altering the encoded amino acid sequence. The cry4Aa-S1 gene allowed a significant improvement in expression level, over five-fold, compared to that of the original cry4Aa gene. The product of the cry4Aa-S1 gene showed the same level of insecticidal activity against Culex pipiens larvae as that from cry4Aa. This suggested that unfavorable codon usage was one of the reasons for poor expression of cry4Aa in E. coli, and, therefore, changing the cry4Aa codons to accord with the codon usage in E. coli led to efficient production of Cry4Aa. Efficient production of Cry4Aa in E. coli can be a powerful measure to prepare a sufficient amount of Cry4Aa protein for both basic analytical and applied researches.

  12. AA, shims and washers on quadrupole ends

    CERN Multimedia

    CERN PhotoLab

    1981-01-01

    Due to the fact that much of the field of the quadrupoles was outside the iron (in particular with the wide quadrupoles) and that thus the fields of quadrupoles and bending magnets interacted, the lattice properties of the AA could not be predicted with the required accuracy. After a first running period in 1980, during which detailed measurements were made with proton test beams, corrections to the quadrupoles were made in 1981, in the form of laminated shims at the ends of the poles, and with steel washers. With the latter ones, further refinements were made in an iterative procedure with measurements on the circulating beam. This eventually resulted, amongst other things, in a very low chromaticity, with the Q-values being constant to within +- 0.001 over the total momentum range of 6 %. Here we see the shims and washers on a narrow qudrupole (QFN, QDN). See also 8103203, 8103204, 8103205, 8103206.

  14. The A&A Experience With Impact Factors

    CERN Document Server

    Sandqvist, A

    2004-01-01

    There is a widespread impression that the scientific journal "Astronomy & Astrophysics" (A&A) has a smaller impact, as measured by citations to articles, than some of the other major astronomy journals. This impression was apparently supported - and probably created - by the Journal Citation Report (JCR), which is prepared annually by the Institute of Scientific Information (ISI) Web of Knowledge. The published poor impact factor of A&A was in fact wrong and was due to a serious flaw in the method used by ISI Web of Knowledge to determine it. The resulting damage inflicted upon A&A by the JCR is incalculable.

    2006-07-01

    The aim of this study was to explore the so-called processing window, within which good-quality welds can be produced, for the friction stir welding of AA5083 to AA6082. To that end a systematic set of nine instrumented welds were made using rotation speeds of 280, 560, and 840 rpm and traverse speeds of 100, 200, and 300 mm/min with AA5083 on the advancing side and another nine with the materials reversed. For comparison a smaller series of AA5083-AA5083 and AA6082-AA6082 welds were also made. Thermocouple measurements, tool torque, extent of material mixing, and macrostructural observations all indicate that the temperature under the tool is more strongly dependent on the rotation than the traverse speed. It was found that in the current case, the power (energy/s) and heat input (energy/mm) do not correlate simply with the weld temperature. As a result, such metrics may not be suitable for characterizing the conditions under which welds are produced.

    Student-generated videos provide an authentic learning experience for students, enhance motivation and engagement, improve communication skills, and improve collaborative learning skills. This article describes the development and implementation of a student-generated video activity as part of a knowledge, observation, simulation, and experience (KOSE) program at the School of Dentistry, International Medical University, Kuala Lumpur, Malaysia. It also reports the students' perceptions of an activity that introduced first-year dental students (n=44) to clinical scenarios involving patients and dental team aiming to improve professional behavior and communication skills. The learning activity was divided into three phases: preparatory phase, video production phase, and video-watching. Students were organized into five groups and were instructed to generate videos addressing given clinical scenarios. Following the activity, students' perceptions were assessed with a questionnaire. The results showed that 86 percent and 88 percent, respectively, of the students agreed that preparation of the activity enhanced their understanding of the role of dentists in provision of health care and the role of enhanced teamwork. In addition, 86 percent and 75 percent, respectively, agreed that the activity improved their communication and project management skills. Overall, the dental students perceived that the student-generated video activity was a positive experience and enabled them to play the major role in driving their learning process.

    Eljaafari, Samira

    Les besoins de reduction du poids se sont concretement traduits par l'introduction de nouvelles nuances plus legeres dans les structures automobiles. Ainsi, des alliages d'aluminium ont commence a etre integres dans les pieces de structure de plusieurs vehicules. La faible masse volumique des alliages d'aluminium (2,7g/cm3) permet d'alleger le poids du vehicule qui entraine une diminution de la consommation de carburant et, donc, des emissions de gaz a effet de serre. La striction et la rupture sont les principaux modes de defaillance qui entrainent le rebut systematique des pieces. C'est pourquoi, ameliorer la prediction d'apparition de ces defauts lors de la simulation va dans le sens d'une meilleure maitrise du procede. Dans le cadre de ce travail doctoral, deux modeles sont developpes pour simuler le comportement a grandes deformations d'alliages d'aluminium: un modele polycristallin de type Taylor et un modele a un ou plusieurs elements finis par grain. Les diagrammes limites de formage (DLF) pour les deux alliages d'aluminium AA5754 et AA6063 ont ete simules numeriquement en utilisant une formulation par elements finis pour les polycristaux basee sur l'hypothese de Taylor. Les DLF conventionnels et de l'hydroformage ont ete traces. L'effet des chemins de deformation sur la formabilite des alliages d'aluminium a aussi ete etudie. Finalement, des simulations numeriques avec les donnees de diffraction des electrons retrodiffuses (EBSD) pour 1'alliage d'aluminium AA5754 ont ete effectuees en utilisant le modele a un ou plusieurs elements par grain. Ces simulations sont executees avec differents modeles du durcissement (Asaro, Bassani et puissance).

    2016-02-21

    The purpose of this study was to investigate how students perceived their learning experience when combining traditional anatomy lectures with preparatory e-learning activities that consisted of fill-in-the-blank assignments, videos, and multiple-choice quizzes. A qualitative study was conducted to explore changes in study behaviour and perception of learning. Three group interviews with students were conducted and thematically analysed. Data was categorized into four themes: 1. Approaching the course material, 2. Understanding the material, 3. Consolidating the material, and 4. Perceived learning outcome. Students appreciated the clear structure of the course, and reported that online activities encouraged them towards a first engagement with the material. They felt that they were more active during in-class sessions, described self-study before the end-of-term exam as easier, and believed that contents would remain in their memories for a longer time. By adjusting already existing resources, lectures can be combined fairly easily and cost-effectively with preparatory e-learning activities. The creation of online components promote well-structured courses, can help minimize 'student passivity' as a characteristic element of lectures, and can support students in distributing their studies throughout the term, thus suggesting enhanced learning. Further research work should be designed to confirm the afore-mentioned findings through objective measurements of student learning outcomes.

    The tensile rupture locations of friction stir welded joints of AA2017-T351 and AA6061-T6 aluminum alloys were examined. The experiments show that the rupture locations of the joints are different for the two aluminum alloys, which are influenced by the welding parameters. When the joints are free of welding defects, the AA2017-T351 joints are ruptured in the weld nugget adjacent to the thermo-mechanically affected zone on the advancing side and the rupture surfaces appear as oval contours of the weld nugget, while the AA6061-T6 joints are ruptured in the heat affected zone on the retreating side and the rupture surfaces are inclined at a certain degree to the bottom surfaces of the joints. When welding defects are present in the joints, the AA2017-T351 joints are ruptured in the weld center, while the AA6061-T6 joints are ruptured on the retreating side near the weld center. The rupture locations of the joints are dependent on the internal structures of the joints and can be explained through them.

  13. Fecal transmission of AA amyloidosis in the cheetah contributes to high incidence of disease

    AA amyloidosis is one of the principal causes of morbidity and mortality in captive cheetahs (Acinonyx jubatus), which are in danger of extinction, but little is known about the underlying mechanisms. Given the transmissible characteristics of AA amyloidosis, transmission between captive cheetahs may be a possible mechanism involved in the high incidence of AA amyloidosis. In this study of animals with AA amyloidosis, we found that cheetah feces contained AA amyloid fibrils that were different from those of the liver with regard to molecular weight and shape and had greater transmissibility. The infectious activity of fecal AA amyloid fibrils was reduced or abolished by the protein denaturants 6 M guanidine·HCl and formic acid or by AA immunodepletion. Thus, we propose that feces are a vehicle of transmission that may accelerate AA amyloidosis in captive cheetah populations. These results provide a pathogenesis for AA amyloidosis and suggest possible measures for rescuing cheetahs from extinction. PMID:18474855

    For each of the 4995 persons listed in the 1989 American Astronomical Society Membership Directory, we noted their total 1984-88 publications as listed in the Author Index of Astronomy and Astrophysics Abstracts. The members are subdivided as retired (mean of 0.61 paper/yr), foreign (3.89), Full (3.34), Division Affiliates (1.76), Associate (1.48), and Junior (0.79) members. For Full members the frequencies of various publication rates are listed; the median is 2.28 papers/yr. The Full members are subdivided by affiliations, namely private institutions (mean of 4.71 papers/yr), university (3.89), government-funded (3.46), commercial company (1.81), and unknown affiliations (0.84). We looked up the listed publications for four high producers who each average 25.7 papers/yr. We found that 55% of those are preprints, abstracts, conference papers, and other secondary material. Furthermore, they average 4.2 authors per original research paper. If we divide each original research paper by the number of authors, these four average only the equivalent of 4.0 single-author research papers/yr. A sample of moderate producers also have 53% of their publications as abstracts, conference papers, etc., and they average 4.2 authors per original research paper. We conclude that the average Full AAS member produces the equivalent of 1/2 single-author original-research paper/yr and 23% of them produce more than 1 such paper/yr.

    Strobbe, Stephen; Thompson, Stephanie M; Zucker, Robert A

    2013-01-01

    Alcohol use disorders and their related consequences continue to be among the nation's most prevalent and persistent healthcare problems across the lifespan. The vast majority of treatment facilities for substance use disorders in the United States report using some form of 12-step facilitation to help direct their patients to mutual help groups such as Alcoholics Anonymous (AA). Yet, many students in various healthcare disciplines may lack familiarity and direct experience with this readily accessible and potentially lifesaving, low-cost resource. AA has a long-standing tradition of extending an open invitation to professionals and providing educational materials about this worldwide program of recovery. The purpose of this article is to describe an experiential, interdisciplinary approach that has been used to teach undergraduate psychology students about AA. Associated activities included (a) selected readings, (b) attendance at an open AA meeting, (c) the formulation of thoughtful questions by the students, and (d) a single, interactive didactic session. Undergraduate psychology students responded positively when principles of experiential learning were applied to educational activities related to AA.

    Objective To investigate the flexibility and mobility of the Bacillus thuringiensis toxin Cry1Aa. Methods The graph theory-based program Constraint Network Analysis and normal mode-based program NMsim were used to analyze the global and local flexibility indices as well as the fluctuation of individual residues in detail. Results The decrease in Cry1Aa network rigidity with the increase of temperature was evident. Two phase transition points in which the Cry1Aa structure lost rigidity during the thermal simulation were identified. Two rigid clusters were found in domains I and II. Weak spots were found in C-terminal domain III. Several flexible regions were found in all three domains;the largest residue fluctuation was present in the apical loop2 of domain II. Conclusion Although several flexible regions could be found in all the three domains, the most flexible regions were in the apical loops of domain II.

    2007-06-01

    To trace the evolution of Alcoholics Anonymous in Ireland from its establishment there in 1946, focusing on the efforts of early members to publicize the fellowship and negotiate a role for themselves in relation to existing religious and healthcare institutions. Archival research, drawing mainly on primary sources in AA archives in New York and Dublin. Anticipated tensions between this fellowship, which had its roots in Evangelical Protestantism, and the politically powerful Roman Catholic Church in Ireland were skillfully avoided; initial hostility from the medical profession quickly dissipated; and AA distanced itself from policy debate on the wider topic of alcoholism as disease. The relatively smooth introduction of AA to Ireland, the first European country in which it was established, may be attributed to the essentially pragmatic nature of the fellowship and the strategic abilities of its early members.

    Editors Note:This is a final post from the 227th AAS Meeting in Kissimmee, FL. This special summary of AAS Hack Day, a meeting of AAS members to collaboratively work on various small projects, was written by Meredith Rawls (@Merrdiff) and was originally posted on astrobites.com.As the 227thAmerican Astronomical Society meeting drew to a close (see highlights from Day 1, Day 2, Day 3, and Day 4), a group of at least 50 attendees spent Day 4working on small projects fondly called hacks. Thanks to sponsorship from LSST and Northrup Grumman, the industrious hackers werewell-caffeinated and fed so we could devote time and energy toworking in groups on one-day projects.TheHack Day beganat 10am with pitches. Anybody with a project idea was welcome to briefly speak and try to convince others to work with them. Only someideas panned out, but the enthusiasm was palpable. Its not every day you get a full room of astronomers and affiliates eager to spend hours working on fun and useful projects to benefit the community.#hackAAS is getting underway! #aas227 pic.twitter.com/yX7jlOnSCK James R A Davenport (@jradavenport) January 8, 2016Here is a rundown of what we accomplished. Pretty impressive for a single day! Many thanks to fellow astrobiter Erika Nesvold (now at Carnegie DTM; @erikanesvold) whose hack was live-documenting all the other hacks. Her tweets as @astrobites appeared with the #hackaas hashtag, and her notes made this recap post infinitely easier to write.Interested in joining the fun? Sign up for Hack Day at the 2017 JanuaryAAS meeting (its free with meeting registration), and consider applying for the .Astronomy conference this summer.Towards Optimal Session Scheduling:Adrian Price-Whelan (Columbia), David Hogg (NYU), and Scott Idem (AAS) began writing a program to take all submitted abstracts to a conference like AAS and sort them using keywords to avoid scheduling similar talks in parallel sessions.

    The present paper emphasizes the friction and wear properties of Carbon Nanotubes reinforced AA 4032 nanocomposites prepared by powder metallurgy technique. CNTs are multi-wall in nature and prepared by electric arc discharge method. Multi-walled CNTs are blended with AA 4032 elemental powders and compaction followed by sintering to get bulk nanocomposites. The strength of the composites has been evaluated by microhardness and the surface contact between the nanocomposites and EN 32 steel has been evaluated by Pin on disk tester. The results are proven that reinforcement of CNTs play a major role in the enhancement of hardness and wear.

    Two horses with chronic uveitis and histological lesions consistent with equine recurrent uveitis (ERU) were examined. Microscopical findings in the ciliary body included deposits of amyloid lining the non-pigmented epithelium, intracytoplasmic, rod-shaped, eosinophilic inclusions and intraepithelial infiltration of T lymphocytes. Ultrastructural examination of the ciliary body of one horse confirmed the presence of abundant extracellular deposits of non-branching fibrils (9-11 nm in diameter) consistent with amyloid. Immunohistochemistry revealed strong positive labelling for AA amyloid and mass spectrometry showed the amyloid to consist primarily of serum amyloid A1 in both cases. The findings suggest that localized, intraocular AA amyloidosis may occur in horses with ERU.

    AA7020 Al–Mg–Zn, a medium strength aluminium alloy, is used in welded structures in military and aerospace applications. As it may be subjected to extremes of environmental exposures, including high pressure liquid hydrogen, it could suffer hydrogen embrittlement. Hydrogen susceptibility of alloy AA7020 was evaluated by slow strain-rate tensile testing, and delayed failure testing of hydrogen-charged specimens of air-cooled, duplexaged, and water-quenched duplex agedmaterials. The resistance to hydrogen embrittlement of the alloy was found to be in the order of air-cooled duplex aged alloy > as-received (T6 condition) > water quenched duplex aged material.

    Full Text Available In this study AA5754 and A6061 alloys have been butt welded to each other by using friction stir welding (FSW. At constant tool geometry and tool angle experiments were carried out, joints were performed using different welding speed, rotation speed and especially tool press force. The mechanical properties of the welded samples were determined by using tensile test, bending test and micro hardness. Generated microstructure and hardness profile was obtained in the welding zone. In this friction stir welding study the parameters which affect the joint structure are the tool press force, welding speed and tool rotation speed which were determined. At the end of study it is determined that AA5754 and AA6061 alloys can be successfully welded by using Friction Stir Welding method under different tool press forces at least 6kN.

    Asticcacaulis excentricus, who lives in upper-layer waters providing food resource to the mosquito larvae and has been proven to be a successful host to produce the mosquitocidal binary toxins or Cry11Aa toxin from Bacilli (Liu et al., 1996, Nat Biotech 14: 343; Armengol, et al. , 2005, Curr Microbiol 51: 430), was developed to express cyt1Aa gene from Bacillus thuringiensis subsp. israelensis (Bti). Two A. excentricus transformants were constructed with the attempt of producing CytlAa alone and alongside with Cry11Aa, repectively. Detection of expressed Cry11Aa and CytlAa proteins by immunoblot in the recombinant A. excentricus clones showed that either cry11Aa or cyt1Aa was expressed well solely but not simultaneously although both restriction analyses of plasmid DNA and DNA sequencing showed that the transformed plasmid was identical to scheme. To investigate the reason why the recombinant A. excentricus harboring both genes and their ribosome binding site (RBS) sequences expressed only Cry11Aa, the total RNA of A. excentricus cells was extracted and revealed three-band pattern in which all RNA molecule weights are not greater than 16S RNA of Escherichia coli by formamide agarose gel electrophoresis, indicating that different RNA systems within these two Gram-negative strains required distinguishingly organised constructs to express multiple foreign genes. It is hypothesized that an extra promoter upstream of RBS sequence is required to express cyt1Aa in the cry11Aa-cyt1Aa tandom plasmid.

    An operative anatomy course was developed within the construct of a surgical internship preparatory curriculum. This course provided fourth-year medical students matching into a surgical residency the opportunity to perform intern-level procedures on cadavers under the guidance of surgical faculty members. Senior medical students performed intern-level procedures on cadavers with the assistance of faculty surgeons. Students' confidence, anxiety, and procedural knowledge were evaluated both preoperatively and postoperatively. Preoperative and postoperative data were compared both collectively and based on individual procedures. Student confidence and procedural knowledge significantly increased and anxiety significantly decreased when preoperative and postoperative data were compared (P < .05). Students reported moderate to significant improvement in their ability to perform a variety of surgical tasks. The consistent improvement in confidence, knowledge, and anxiety justifies further development of an operative anatomy course, with future assessment of the impact on performance in surgical residency.

  12. Social support and comfort in AA as mediators of "Making AA easier" (MAAEZ), a 12-step facilitation intervention.

    Subbaraman, Meenakshi Sabina; Kaskutas, Lee Ann

    2012-12-01

    A trial of "Making Alcoholics Anonymous Easier" (MAAEZ), a group-format 12-step facilitation program, showed significantly higher odds of past 30-day abstinence after 12 months among those who had been treated in MAAEZ compared to usual care, especially for clients with high prior AA/NA/CA meeting attendance (>90 prior meetings; OR = 2.94, p = .02). We examined whether MAAEZ effects for this group were mediated by social support for sobriety and comfort with the 12-step fellowship. Among those with high prior AA/NA/CA attendance, we performed tests of multiple mediation to estimate MAAEZ effects attributable to the combined effect of social network support for sobriety, comfort being at AA/NA/CA meetings, and comfort speaking at AA/NA/CA meetings. To gain some understanding of sustaining these behaviors, we also examined each potential mediating variable measured both prior to, and concurrent with, 12-month outcomes. Having support for sobriety at 6 months emerged as a mediator of 12-month MAAEZ effects, when controlling for comfort being and speaking at AA/NA/CA meetings at 6 months. The effect remained when controlling for mediator values at 12 months, and explained 44% of the MAAEZ effect. Results highlight the value of studying specific, modifiable 12-step activities, and demonstrate the importance of exploring subgroups to determine behaviors and attitudes to target for optimal treatment. For example, increasing support for sobriety among those with high prior AA/NA/CA attendance may be especially pertinent. 2013 APA, all rights reserved

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

  16. The effect of high school chemistry instruction on students' academic self-concept

    Science.gov (United States)

    Morgan, Peter Wallace

    The purpose of this study was to investigate the effect of extended instruction in high school chemistry on the academic self-concept of students and determine what parts of the learning experience need to be addressed to make the interaction a more positive one. Fifty-seven students from three metropolitan public schools, who were enrolled in college preparatory chemistry classes, were asked to complete a written instrument, before and after extended chemistry instruction, that measures academic self-concept. Twenty-one of the students who took part in the written task volunteered to answer some in-depth interview questions concerning their academic self-concept and its relationship to chemistry instruction. Student responses, instrument scores, and student chemistry grades were analyzed for a variety of chemistry learning--academic self-concept connections and interactions. Results showed that there was a positive interaction for less than half of the students involved in the interview sessions. The results from the written instrument showed similar findings. Comparing chemistry grades and academic self-concept revealed an uncertain connection between the two, especially for students with strong academic self-concepts. Students felt that the laboratory experience was often disconnected from the remainder of chemistry instruction and recommended that the laboratory experience be integrated with classroom work. Students also expressed concerns regarding the volume of algorithmic mathematical calculations associated with college preparatory chemistry instruction. Results of this study suggest that secondary chemistry instruction must become more aware of the affective domain of learning and develop a mindful awareness of its connection to the cognitive domain if chemistry teaching and learning is going to better facilitate the intellectual growth of secondary students.

  20. New perspectives on contributing factors to the monthly behavior of the aa geomagnetic index

    Science.gov (United States)

    Mendoza, Blanca; Pazos, Marni; González, Luis Xavier

    2016-12-01

    We studied the Aa geomagnetic index ( aa index daily average) behavior on a monthly timescale using data from 1868 to 2015 for cycles 11-24. We identified solar- and lunar-associated periodicities in the Aa time series and found statistically significant Aa minima values a few days before the full Moon and high Aa values during the new Moon. When considering all the cycles, it was clear that the deepest Aa minima occurred during the Aa descending activity phase. However, when the cycles were separated according to the direction of the interplanetary magnetic field (IMF), the Aa minima came from the contribution of cycles with the IMF pointing toward the Sun (Type 1). Furthermore, during the descending phase of cycles with the IMF pointing away from the Sun (Type 2), the smallest Aa index values were found along with smaller changes compared to Type 1 cases. This behavior implies that during Type 1 cycles there are larger Aa perturbations than during Type 2 cycles. It is very likely that the mechanisms responsible for the Aa monthly behavior are a combination of solar and lunar effects that depend on several factors: (a) the Moon phases (new and full Moon), (b) the phase of the solar cycle (ascending or descending), and (c) the direction of the interplanetary magnetic field (away or toward the Sun).

  1. Core-corona PSt/P(BA-AA) composite particles by two-stage emulsion polymerization

    Science.gov (United States)

    Xie, Delong; Ren, Xiaolin; Zhang, Xinya; Liao, Shijun

    2016-03-01

    Raspberry-shaped composite particles with polystyrene (PSt) as core and poly(n-butyl acrylate-co-acrylic acid) (P(BA-AA)) as corona were synthesized via emulsion polymerization. The random copolymer, P(BA-AA), was pre-prepared and used as a polymeric surfactant, its emulsifying properties adjusted by changing the mass ratio of BA and AA. The morphology of the resulting core-corona composite particles, P(St/P(BA-AA)), could be regulated and controlled by varying the concentrations of P(BA-AA) or the mass ratio of BA:AA in P(BA-AA). The experimental results indicate that 3.0-6.0 wt% of P(BA-AA) is required to obtain stable composite emulsions, and P(BA-AA) with a mass ratio of BA:AA = 1:2 is able to generate distinct core-corona structures. A mechanism of composite particle formation is proposed based on the high affinity between the PSt core and the hydrophobic segments of P(BA-A). The regular morphology of the colloidal film is expected to facilitate potential application of core-corona particles in the field of light scattering. Furthermore, the diversity of core-corona particles can be expanded by replacing P(BA-AA) corona particles with other amphiphilic particles.

  2. Serum amyloid A and protein AA: molecular mechanisms of a transmissible amyloidosis.

    Science.gov (United States)

    Westermark, Gunilla T; Westermark, Per

    2009-08-20

    Systemic AA-amyloidosis is a complication of chronic inflammatory diseases and the fibril protein AA derives from the acute phase reactant serum AA. AA-amyloidosis can be induced in mice by an inflammatory challenge. The lag phase before amyloid develops can be dramatically shortened by administration of a small amount of amyloid fibrils. Systemic AA-amyloidosis is transmissible in mice and may be so in humans. Since transmission can cross species barriers it is possible that AA-amyloidosis can be induced by amyloid in food, e.g. foie gras. In mice, development of AA-amyloidosis can also be accelerated by other components with amyloid-like properties. A new possible risk factor may appear with synthetically made fibrils from short peptides, constructed for tissue repair.

    2012-01-01

    Empirical findings characterizing long-term, committed Alcoholics Anonymous (AA) members are limited, particularly among younger members. The authors studied a sample of 266 highly committed attendees (mean age, 27 years) at an annual conference of Young People in Alcoholics Anonymous (YPAA), whose first encounter with AA was 6 years previously. Most (72%) had abused drugs and alcohol, and 36% had never received substance abuse treatment. They now reported a mean duration of abstinence of 44 months and had attended an average of 233 AA meetings in the previous year; 66% had served as AA sponsors, and 92% reported experiencing an AA "spiritual awakening," itself associated with a decreased likelihood of alcohol craving. Scores on AA beliefs, affiliation to other members, and the experience of spiritual awakening were associated with lower depression scores. These findings are discussed to clarify the nature of long-term AA membership.

  4. Property Evaluation of Friction Stir Welded Dissimilar Metals : AA6101-T6 and AA1350 Aluminium Alloys

    Rajendran ASHOK KUMAR

    2017-02-01

    Full Text Available Next to copper, aluminium alloys are widely used in electrical industries, because of their high electrical conductivity. AA6101-T6 and AA1350 aluminium alloys are widely used in electrical bus bars. As these alloys are joined by mechanical fasteners in electrical bus bars, the conductive area has been reduced. To avoid this problem, they should be joined without removal of metal as well as their properties. Friction stir welding technique is mainly invented for joining similar and dissimilar aluminium alloys. In this investigation, friction stir welding of AA6101-T6 and AA1350 aluminium alloys was done by varying tool traversing speed, rotational speed and tilt angle with hexagonal pin profiled tool. The analysis of variance was employed to study the effect of above parameters on mechanical properties of welded joints. From the experimental results, it is observed that welded joint with the combination of 1070 rpm rotating speed, 78 mm/min traversing speed and 2° tilt angle provides better mechanical properties. Analysis of variance shows that most significant impact on tensile strength is made by variation in tool rotating speed while tool tilt angle makes the most significant impact on elongation and bending strength.DOI: http://dx.doi.org/10.5755/j01.ms.23.1.14132

  5. A Profile Analysis of Raman-scattered O VI Bands at 6825 \\AA\\ and 7082 \\AA\\ in Sanduleak's Star

    2016-01-01

    We present a detailed modeling of the two broad bands observed at 6825 \\AA\\ and 7082 \\AA\\ in Sanduleak's star, a controversial object in the Large Magellanic Cloud. These bands are known to originate from Raman-scattering of O VI $\\lambda\\lambda$ 1032 and 1038 photons with atomic hydrogen and are only observed in bona fide symbiotic stars. Our high-resolution spectrum obtained with the Magellan Inamori Kyocera Echelle (MIKE) spectrograph at the Magellan-Clay Telescope reveals, quite surprisingly, that the profiles of the two bands look very different: while the Raman 6825 \\AA\\ band shows a single broad profile with a redward extended bump, the Raman 7082 \\AA\\ band exhibits a distinct triple-peak profile. Our model suggests that the O VI emission nebula can be decomposed into a red, blue and central emission regions from an accretion disk, a bipolar outflow and a further compact, optically thick region. We also perform Monte Carlo simulations with the aim of fitting the observed flux ratio $F(6825)/F(7082) \\si...

  6. Microstructure and Mechanical Properties of Accumulative Roll-Bonded AA1050A/AA5005 Laminated Metal Composites

    2016-03-01

    Full Text Available Laminated metal composites (LMCs with alternating layers of commercial pure aluminum AA1050A and aluminum alloy AA5005 were produced by accumulative roll-bonding (ARB. In order to vary the layer thickness and the number of layer interfaces, different numbers of ARB cycles (4, 8, 10, 12, 14 and 16 were performed. The microstructure and mechanical properties were characterized in detail. Up to 8 ARB cycles, the ultrafine-grained (UFG microstructure of the layers in the LMC evolves almost equally to those in AA1050A and AA5005 mono-material sheets. However, the grain size in the composites tends to have smaller values. Nevertheless, the local mechanical properties of the individual layers in the LMCs are very similar to those of the mono-material sheets, and the macroscopic static mechanical properties of the LMCs can be calculated as the mean value of the mono-material sheets applying a linear rule of mixture. In contrast, for more than 12 ARB cycles, a homogenous microstructure was obtained where the individual layers within the composite cannot be visually separated any longer; thus, the hardness is at one constant and a high level across the whole sheet thickness. This results also in a significant higher strength in tensile testing. It was revealed that, with decreasing layer thickness, the layer interfaces become more and more dominating.

  7. Value analysis: a method for teaching nursing ethics and promoting the moral development of students.

    Science.gov (United States)

    Frisch, N C

    1987-10-01

    In an investigation of junior-level baccalaureate nursing students, the value analysis teaching strategy was used to teach content related to nursing ethics. It was hypothesized that such a strategy, which emphasized the need for careful evaluation and weighing of facts preparatory to drawing conclusions, would impact on the student's level of cognitive moral development. Cognitive moral development was defined in accord with Kohlberg's theory of moral development. Control and experimental populations were derived from two groups of students sequentially enrolled in the same course. Pre- and post-testing using scores on Rest's Defining Issues Test (DIT) showed significant differences in gain between control and experimental subjects. There was a strong association between DIT score gains and self-report of peer discussion of ethical issues. The major implication of this study is that instructional intervention produces measurable change in some students' level of moral judgment.

    Herein, we report cloning and analysis of promoters of GLABRA2 (AaGL2) homolog and a MIXTA-Like (AaMIXTA-Like1) gene from Artemisia annua. The upstream regulatory regions of AaGL2 and AaMIXTA-Like1 showed the presence of several crucial cis-acting elements. Arabidopsis and A. annua seedlings were transiently transfected with the promoter-GUS constructs using a robust agro-infiltration method. Both AaGL2 and AaMIXTA-Like1 promoters showed GUS expression preferentially in Arabidopsis single-celled trichomes and glandular as well as T-shaped trichomes of A. annua. Transgenic Arabidopsis harboring constructs in which AaGL2 or AaMIXTA-Like1 promoters would control GFP expression, showed fluorescence emanating specifically from trichome cells. Our study provides a fast and efficient method to study trichome-specific expression, and 2 promoters that have potential for targeted metabolic engineering in plants.

    We report a 12-year-old boy with nephrotic syndrome due to renal AA amyloidosis. The AA amyloidosis was associated with a 3-year history of systemic-onset juvenile idiopathic arthritis. The presence of serum amyloid A protein was confirmed by laser microdissection of Congo Red-positive glomeruli and vessels followed by liquid chromatography and tandem mass spectrometry; this analysis excluded hereditary and familial amyloidosis. Aggressive management of the systemic-onset juvenile idiopathic arthritis resulted in improvement in clinical and laboratory parameters. The case represents an unusual cause of nephrotic syndrome in children. Early diagnosis of renal amyloidosis and management of systemic-onset juvenile idiopathic arthritis is paramount to preventing progression of kidney disease.

  11. Co-expression of AaPMT and AaTRI effectively enhances the yields of tropane alkaloids in Anisodus acutangulus hairy roots

    Science.gov (United States)

    2011-01-01

    Background Tropane alkaloids (TA) including anisodamine, anisodine, hyoscyamine and scopolamine are a group of important anticholinergic drugs with rapidly increasing market demand, so it is significant to improve TA production by biotechnological approaches. Putrescine N-methyltransferase (PMT) was considered as the first rate-limiting upstream enzyme while tropinone reductase I (TRI) was an important branch-controlling enzyme involved in TA biosynthesis. However, there is no report on simultaneous introduction of PMT and TRI genes into any TA-producing plant including Anisodus acutangulus (A. acutangulus), which is a Solanaceous perennial plant that is endemic to China and is an attractive resource plant for production of TA. Results In this study, 21 AaPMT and AaTRI double gene transformed lines (PT lines), 9 AaPMT single gene transformed lines (P lines) and 5 AaTRI single gene transformed lines (T lines) were generated. RT-PCR and real-time fluorescence quantitative analysis results revealed that total AaPMT (AaPMT T) and total AaTRI (AaTRI T) gene transcripts in transgenic PT, P and T lines showed higher expression levels than native AaPMT (AaPMT E) and AaTRI (AaTRI E) gene transcripts. As compared to the control and single gene transformed lines (P or T lines), PT transgenic hairy root lines produced significantly higher levels of TA. The highest yield of TA was detected as 8.104 mg/g dw in line PT18, which was 8.66, 4.04, and 3.11-times higher than those of the control (0.935 mg/g dw), P3 (highest in P lines, 2.004 mg/g dw) and T12 (highest in T lines, 2.604 mg/g dw), respectively. All the tested samples were found to possess strong radical scavenging capacity, which were similar to control. Conclusion In the present study, the co-expression of AaPMT and AaTRI genes in A. acutangulus hairy roots significantly improved the yields of TA and showed higher antioxidant activity than control because of higher total TA content, which is the first report on

  13. Wooden models of an AA quadrupole between bending magnets

    CERN Multimedia

    1978-01-01

    At two points in the AA lattice, a quadrupole (QDN, defocusing, narrow) was tightly wedged between two bending magnets (BST, short, wide). This picture of wooden models lets one imagine the strong interaction between their magnetic fields. There was no way one could calculate with the necessary accuracy the magnetic effects and their consequences for the machine optics. The necessary corrections were made after measurements with a circulating beam, in a tedious iterative procedure, with corrrection coils and shims.

    Proton induced X-ray emission analysis results are reported for obsidian artifacts from different sites of the State of Mexico: Teotenango, Calixtlahuaca, La Marqueza, Malinalco and Tonatico. Twenty elements were analysed by PIXE and some of them were verified by AAS. The results show that the samples came from three different sources: Teotenango and Calixtlahuaca samples from the first, La Marqueza and Malinalco samples from the second and Tonatico samples from the third.

  15. AA patterns for point sets with controlled spectral properties

    OpenAIRE

    2015-01-01

    We describe a novel technique for the fast production of large point sets with different spectral properties. In contrast to tile-based methods we use so-called AA Patterns: ornamental point sets obtained from quantization errors. These patterns have a discrete and structured number-theoretic nature, can be produced at very low costs, and possess an inherent structural indexing mechanism equivalent to those used in recursive tiling techniques. This allows us to generate, manipulate and store ...

    2016-01-01

    Near-Earth asteroid 2014 AA entered the Earth's atmosphere on 2014 January 2, only 21 hours after being discovered by the Catalina Sky Survey. In this paper we compute the trajectory of 2014 AA by combining the available optical astrometry, seven ground-based observations over 69 minutes, and the International Monitoring system detection of the atmospheric impact infrasonic airwaves in a least-squares orbit estimation filter. The combination of these two sources of observations results in a tremendous improvement in the orbit uncertainties. The impact time is 3:05 UT with a 1-sigma uncertainty of 6 min, while the impact location corresponds to a west longitude of 44.7 deg and a latitude of 13.1 deg with a 1-sigma uncertainty of 140 km. The minimum impact energy estimated from the infrasound data and the impact velocity result in an estimated minimum mass of 22.6 t. By propagating the trajectory of 2014 AA backwards we find that the only window for finding precovery observations is for the three days before it...

    Full Text Available Background: The natural history of AA amyloidosis is typically progressive, leading to multiple organ failure and death. We analyzed the etiology as well as clinical and laboratory features of patients with biopsy-proven AA amyloidosis and evaluated the ultimate outcome. Methods: Seventy-three patients (24 female; mean age 41.85±15.89 years were analyzed retrospectively. Demographic, clinical and laboratory features were studied and the outcome was assessed. Results: Familial Mediterranean Fever and tuberculosis were the most frequent causes of amyloidosis. Mean serum creatinine and proteinuria at diagnosis were 4.65±4.89 mg/dl and 8.04±6.09 g/day, respectively; and stage I, II, III, IV and V renal disease were present in 19.2%, 13.7%, 16.4%, 11%, and 39.7% of the patients, respectively. ESRD developed in 16 patients during the follow-up period. All of the ESRD patients started a dialysis programme. Thirty patients (41% died during the follow-up period; median patient survival was 35.9±6.12 months. Old age, tuberculosis etiology, advanced renal disease and low serum albumin levels were associated with a worse prognosis. Serum albumin was a predictor of mortality in logistic regression analysis. Conclusion: The ultimate outcome of the patients with AA amyloidosis is poor, possibly due to the late referral to the nephrology clinics. Early referral may be helpful to improve prognosis.

  2. Effects of Friction Stir Welding Speed on AA2195 alloy

    2016-01-01

    Full Text Available The application of friction stir welding (FSW to aerospace has grown rapidly due to the high efficiency and environmental friendly nature of the process. FSW is achieved by plastic flow of frictionally heated material in solid state and offers many advantages of avoiding hot cracking and limiting component distortion. Recently low density, high modulus and high strength AA2195 are used as substitute for conventional aluminum alloys since the weight saving is critical in aerospace applications. One of the problems for this alloy is weld metal porosity formation leading to hot cracking. Combination of FSW and AA2195 provides synergy effect to improve mechanical properties and weight saving of aerospace structure such as cryogenic fuel tanks for launch systems. The objective of this paper is to investigate the effect of friction stir welding speed on mechanical and microstructural properties of AA2195. The friction stir welded materials were joined with four different tool rotation speeds (350~800 rpm and five welding speeds (120~360 mm/min, which are the two prime welding parameters in this process.

    Vegetative insecticidal protein (Vip3) from Bacillus thuringiensis shows high activity against lepidopteran insects. Cytolytic δ-endotoxin (Cyt) also has high toxicity to dipteran larvae and synergism with other crystal proteins (Cry), but synergism between Cyt and Vip3 proteins has not been tested. We analyzed for synergism between Cyt2Aa3 and Vip3Aa29. Both cyt2Aa3 and vip3Aa29 genes were co-expressed in Escherichia coli strain BL21 carried on vector pCOLADuet-1. Vip3Aa29 showed insecticidal activity against Chilo suppressalis and Spodoptera exigua, with 50% lethal concentration (LC(50)) at 24.0 and 36.6 μg ml(-1), respectively. It could also inhibit Helicoverpa armigera growth, with 50% inhibition concentration at 22.6 μg ml(-1). While Cyt2Aa3 was toxic to Culex quinquefasciatus (LC(50): 0.53 μg ml(-1)) and Chironomus tepperi (LC(50): 36 μg ml(-1)), it did not inhibit C. suppressalis, S. exigua, and H. armigera. However, the co-expression of Cyt2Aa3 and Vip3Aa29 showed synergistic effect on C. suppressalis and S. exigua, and the individual activities were strengthened 3.35- and 4.34-fold, respectively. The co-expression had no synergism against C. tepperi and H. armigera, but exerted some antagonistic effect on Cx. quinquefasciatus. The synergism between Cyt2Aa and Vip3Aa was thus discovered for the first time, which confirmed that Cyt toxin can enhance the toxicity of other toxins against some non-target insects. By synergism analysis, the effectiveness of microbial insecticides can be verified.

    The through-thickness annealing behavior of a laminated AA3xxx–AA6xxx alloy system at 300 °C has been studied by scanning electron microscopy, electron backscatter diffraction analysis, electron probe micro-analysis, differential scanning calorimetry, and hardness measurement. Results show that the recrystallization process starts at the interface region between the AA3xxx (clad) and AA6xxx (core) layers. Subsequently, the recrystallization process front progresses into the core layer, while the clad layer is the last region to recrystallize. It is also found that precipitation precedes recrystallization in the entire laminate at the investigated temperature. The preferential onset of recrystallization at the interface region is attributed to the net driving pressure being the highest in this region. The factors that lead to such enhanced net driving pressure are (a) deformation incompatibility between the two alloy layers, (b) lower solute content of the interface, which also leads to lower volume fraction of precipitates, and (c) an accelerated rate of precipitate coarsening due to the presence of a higher density of dislocations. The gradual progress of recrystallization from the interface towards the core layer is dictated by precipitate coarsening and the dependence of its rate on the density of deformation-induced dislocations. The lower driving pressure due to lower work hardening capacity, high solute drag pressure due to Mn, and additional Zener drag from precipitates that form due to solute redistribution during annealing explain the late initiation of recrystallization in the clad layer. - Highlights: • The through-thickness recrystallization of a laminated system is investigated. • The early onset of recrystallization at the interface is discussed. • The effects of precipitation and coarsening on recrystallization are analyzed.

    Full Text Available Abstract Background This study investigates the use of anabolic androgenic steroids (AAS among a national representative sample of high school students in Iceland. We test several hypotheses drawn from three perspectives. The first perspective focuses on the use of AAS as an individual phenomenon motivated by the desire to succeed in sport. The second perspective views the use of AAS as shaped by norms and values embedded in social relationships of formally organized sport. The third perspective suggests that factors outside sport, which have been shown to correlate with the use of other substances, predict the use of AAS. Method We use logistic regression and predicted probabilities to analyze data from a national representative survey of 11031 Icelandic high school students. Results Our results indicated that the use of AAS is not significantly related to participation in formally organized sports. However, it positively relates to fitness and physical training in informal contexts. We found a relatively strong relationship between the use of AAS and the use of illicit substances and a moderate relationship between AAS use and alcohol and tobacco consumption. We also found a significant negative relationship between AAS use and school integration and school achievement, and a significant positive relationship between AAS use and school anomie. The relation between AAS use and family-related variables was weaker. Finally, we found that the relationship between sport participation, physical exercise, and AAS use varies across levels of anomie and integration. Conclusion Our findings suggest that the use of AAS and especially illegal substances should be considered more as a social and a health problem rather than a sport specific issue. We found that high school students participating in fitness and informal training outside of formally organized sport clubs are the main risk group and should be the target of prevention efforts.

    AA6061 alloy is a widely used material in the automotive and aerospace industries, but is prone to hot cracking, which limits its weldability. To prevent this phenomenon, the AA6061/AA5754 composite was formed using a severe plastic deformation technique, Cross Accumulative Roll Bonding (CARB), at an elevated temperature (350 °C) to ensure good bonding between layers. This technique was efficient to maintain a small grain size, even under the process temperature conditions, and consequently, preserve good mechanical properties. The composite had better mechanical properties than the initial aluminium alloys. Microstructure and texture remained stable after two cycles and yield stress tended towards an equal value in the rolling and the transverse directions. After two cycles, the main component was the {001}〈110〉 rotated Cube, which was maintained for up to 10 cycles. Diffusion was more effective as the strain increased. Finally, a tungsten inert gas (TIG) welding process was performed on the composite and confirmed resistance to hot cracking.

    Cadherin plays an important role in the toxicity of Bacillus thuringiensis Cry proteins. We previously cloned a full-length cadherin from Aedes aegypti larvae and reported this protein binds Cry11Aa toxin from B. thuringiensis subsp. israelensis with high affinity, ≈16.7nM. Based on these results, we investigated if Aedes cadherin is involved in the in vivo toxicity of Cry11Aa toxin to Ae. aegypti. We established a mosquito cell line stably expressing the full-length Aedes cadherin and transgenic mosquitoes with silenced Aedes cadherin expression. Cells expressing the Aedes cadherin showed increased sensitivity to Cry11Aa toxin. Cry11Aa toxin at 400nM killed approximately 37% of the cells in 3h. Otherwise, transgenic mosquitoes with silenced Aedes cadherin expression showed increased tolerance to Cry11Aa toxin. Furthermore, cells expressing Aedes cadherin triggered Cry11Aa oligomerization. These results show the Aedes cadherin plays a pivotal role in Cry11Aa toxicity to Ae. aegypti larvae by mediating Cry11Aa oligomerization. However, since high toxicity was not obtained in cadherin-expressing cells, an additional receptor may be needed for manifestation of full toxicity. Moreover, cells expressing Aedes cadherin were sensitive to Cry4Aa and Cry11Ba, but not Cry4Ba. However transgenic mosquitoes with silenced Aedes cadherin expression showed no tolerance to Cry4Aa, Cry4Ba, and Cry11Ba toxins. These results suggest that while Aedes cadherin may mediate Cry4Aa and Cry11Ba toxicity, this cadherin but is not the main receptor of Cry4Aa, Cry4Ba and Cry11Ba toxin in Ae. aegypti.

    2012-04-01

    AA amyloidosis is a disorder characterized by the abnormal formation, accumulation and systemic deposition of fibrillary material that frequently involves the kidney. Recurrent AA amyloidosis in the renal allograft has been documented in patients with tuberculosis, familial Mediterranean fever, ankylosing spondylitis, chronic pyelonephritis and rheumatoid arthritis. De novo AA amyloidosis is rarely described. We report two cases of AA amyloidosis in the renal allograft. Our first case is a 47-year-old male with a history of ankylosing spondylitis who developed end-stage renal disease reportedly from tubulointerstitial nephritis from non-steroidal anti-inflammatory agent use. A biopsy was never performed. One year after transplantation, AA amyloidosis was identified in the femoral head and 8 years post-transplantation, AA amyloidosis was identified in the renal allograft. He was treated with colchicine and adalimumab and has stable renal function at 1 year-follow-up. Our second case is a 57-year-old male with a long history of intravenous drug use and hepatitis C infection who developed end-stage kidney disease due to AA amyloidosis. Our second patient's course was complicated by renal adenovirus, pulmonary aspergillosis and hepatitis C with AA amyloidosis subsequently being identified in the allograft 2.5 years post-transplantation. Renal allograft function remains stable 4-years post-transplantation. These reports describe clinical and pathologic features of two cases of AA amyloidosis presenting with proteinuria and focal involvement of the renal allograft.

    Many Bachelor of Midwifery students have not had any exposure to the hospital setting prior to their clinical placement. Students have reported their placements are foreign to them, with a specialised confusing 'language'. It is important to provide support to students to prevent culture shock that may lead to them leaving the course. To assist first year midwifery students with the transition into clinical practice by providing a preparatory workshop. An action research project developed resources for a workshop held prior to students' first clinical placement. Four phases were held: Phase one involved holding discussion groups with students returning from clinical practice; Phase two was the creation of vodcasts; Phase three was integration of resources into the clinical subject and phase four was the evaluation and reflection on the action research project. Evaluations of the workshops were undertaken through surveying the students after they returned from their clinical placement. A descriptive analysis of the evaluations was performed. Students rated the workshop, vodcasts and the simulated handover positively. Further recommendations were that complications of labour and birth be included in their first semester as students were unexpectedly exposed to this in their first clinical placement. The students evaluated the workshop positively in reducing the amount of culture shock experienced on the first clinical placement. In addition the students provided further recommendations of strategies that would assist with clinical placement. Copyright © 2014 Australian College of Midwives. Published by Elsevier Ltd.

    2009-06-01

    The development of a personal philosophical statement about nursing is a useful assignment for both undergraduate and graduate nursing students. Students are asked to write a paper describing their philosophical views about nursing related to the metaparadigm concepts and include in-depth examples from their clinical practice to illustrate these views. This article includes information regarding important preparatory activities and handouts to facilitate the writing and evaluation of this assignment. There are many potential benefits of this complex assignment. It promotes students' reflection on their personal clinical practice experiences and engages students in mental and verbal dialogue that elicits their philosophical ideas about the metaparadigm concepts. These activities promote critical thinking and reflective clinical practice, act as a foundation for building theoretical understanding, and promote confidence in learning about nursing and other theories.

    Full Text Available Normal 0 21 false false false TR X-NONE X-NONE MicrosoftInternetExplorer4 The purpose of this study is to identify teacher and student views regarding the Placement Test (SBS. The research was undertaken with primary school teachers from Bolu central district (n=100 and students who were given the test during (n=100 2009-2010 educational year. The study employing the survey model utilizes qualitative research methods. Data was collected by using interview forms which were later analyzed by content analysis. At the end of the study it was found that SBS creates feelings such as stress, fear, anxiety and curiosity and has an important effect on the identification of the future educational lives and professions of the students. SBS prevents students from socializing. Differences have been detected between the courses SBS covers and the courses studied at school. Students engage in activities such as answering test questions, taking trial tests, answering preparatory courses, receiving counseling, going to the courses and private tutoring. School administrators take the exam results very seriously. Implementations that are based on student-teacher-parent collaboration and that use selection based on ability and interests have been suggested.

    Acinetobacter baumannii is an important nosocomial pathogen that causes a high morbidity and mortality rate in infected patients with sepsis form. The surface exposed virulence proteins and serum resistance factors helping to dissemination of this bacterium to bloodstream are the most promising vaccine candidates against this microorganism. In this project we immunologically evaluated OMV(PagL)+Bap(1-487aa) and AbOmpA (8-346aa)+Bap(1-487aa) as combination forms as well as Bap(1-487aa), AbOmpA(8-346aa) and OMV(PagL) singly, with addition of alum adjuvant as vaccine candidates. The titers of total IgG, IgG1 and IgG2c as well as concentration of IL-4 and IFN-γ and survival rates were measured in a C57BL/6 murine model with disseminated sepsis. The ratio of IgG1/IgG2c and profile of IL-4/IFN-γ in OMV (PagL)+Bap (1-487aa) formulation shows the humoral and cellular immune responses have been induced robustly and have created a full protection against A. baumannii ATCC 19606 and MDR AB-44 strains. We found that the two combination vaccine candidates were protective and induced both Th1 and Th2 responses. Copyright © 2015 Elsevier Ltd. All rights reserved.

The maximum gel fraction of pure P(AA and P(AA-co-AMPS hydrogel was found to be 95.2% and 89.6% for P(AA and P(AA-co-AMPS, respectively at a total dose of 20 kGy. Effects of immobilization conditions such as radiation dose, MBAA concentration, comonomer composition and amount of GI were investigated. The influence of reaction conditions on the activity of immobilized GI were studied, the optimum pH value of the reaction solution is 7.5 and reaction temperature is 65 °C. The immobilized GI into P(AA-co-AMPS and P(AA polymer networks retained 81% and 69%, respectively of its initial activity after recycled for 15 times while it retained 87% and 71%, respectively of its initial activity after stored at 4 °C for 48 days. The Km values of free and immobilized GI onto P(AA-co-AMPS and onto P(AA matrices were found to be 34, 29.2 and 14.5 mg/mL, respectively while the Vmax Values calculated to be 3.87, 1.6 and 0.79 mg/mL min, respectively. GI entrapped into P(AA-co-AMPS hydrogel show promising behavior that may be useful as the newly glucose isomerase reactor in biomedical applications.

    Full Text Available Plants are sessile organisms, and they can not move away under abiotic or biotic stresses. Thus plants have evolved a set of genes that response to adverse environment to modulate gene expression. In this study, we characterized and functionally studied an ERF transcription factor from Artemisia annua, AaERF1, which plays an important role in biotic stress responses. The AaERF1 promoter had been cloned and GUS staining results of AaERF1 promoter-GUS transgenic A. annua showed that AaERF1 is expressed ubiquitiously in all organs. Several putative cis-acting elements such as W-box, TGA-box and Py-rich element, which are involved in defense responsiveness, are present in the promoter. The expression of AaERF1 can be induced vigorously by methyl jasmonate as well as by ethephon and wounding, implying that AaERF1 may activate some of the defense genes via the jasmonic acid and ethylene signaling pathways of A. annua. The results of electrophoretic mobility shift assay (EMSA and yeast one-hybrid experiments showed that AaERF1 was able to bind to the GCC box cis-acting element in vitro and in yeast. Ectopic expression of AaERF1 could enhance the expression levels of the defense marker genes PLANT DEFENSIN1.2 (PDF1.2 and BASIC CHITINASE (ChiB, and increase the resistance to Botrytis cinerea in the 35S::AaERF1 transgenic Arabidopsis. The down-regulated expression level of AaERF1 evidently reduced the resistance to B. cinerea in A. annua. The overall results showed that AaERF1 positively regulated the resistance to B. cinerea in A. annua.

    2014-01-01

    In response to two White Papers submitted to the Astro2010 Decadal Survey (1,2), a new AAS Working Group on Astroinformatics and Astrostatistics (WGAA) has been approved by the AAS Council at the 220th Meeting, June 2012, in Anchorage. The motivation for this WG is the growing importance of the interface between astronomy and various branches of applied mathematics, computer science and the emerging field of data science. With the new data-intensive projects envisioned for the coming decade, the need for advice derived from the focused attention of a group of AAS members who work in these areas is bound to increase. The Working Group is charged with spreading awareness of rapidly advancing computational techniques, sophsticated statistical methods, and highly capble software to further the goals of astronomical and astrophysical research. The three main strategic goals adopted by the WGAA Steering Committee for the next few years are to: (i) develop, organize and maintain methodological resources (such as software tools, papers, books, and lectures); (ii) enhance human resources (such as foster the creation of career paths, establish a Speakers' Bureau, establish and maintain an archived discussion forum, enable periodic news distribution); and (iii) organize topical meetings. The WGAA Steering Committee at this time includes twelve members: Kirk Borne, George Djorgovski, Eric Feigelson, Eric Ford, Alyssa Goodman, Joe Hilbe, Zeljko Ivezic (chair), Ashish Mahabal, Aneta Siemiginowska, Alex Szalay, Rick White, and Padma Yanamandra-Fisher.

    A "slotted transmission line" structure was used for both pickups and the kicker of one of the stochastic cooling systems of the Antiproton Accumulator (AA). They served for the cooling of the high-density stack, in momentum and in both transverse planes. In the beginning in a single band, 1-2 GHz, later in 3 bands, 1-2, 2-4 and 4-8 GHz. The kicker of the first generation, shown here, was located where the dispersion was zero and the beam size small, and thus had a quadratic cross-section. The pickups were rectangular and wider in the horizontal plane. See also 7906193

    2013-01-01

    It is fundamental to the advancement of science that practicing scientists adhere to a consistent set of professional ethical principles. Recent violations of these principles have led a decreased trust in the process of science and scientific results. Although astronomy is less in the spotlight on these issues than medical science or climate change research, it is still incumbent on the field to follow sound scientific process guided by basic ethical guidelines. The American Astronomical Society, developed a set of such guidelines in 2010. This contribution summarizes the motivation and process by which the AAS Ethics Statement was produced.

    2016-01-01

    We studied the variability of the magnetic O-type supergiant $\\zeta$ Ori Aa using multi-colour BRITE photometry. We confirmed the known rotation frequency $f_{\\rm rot} = 0.15 \\pm 0.02$ c/d, and detected some of its higher harmonics, of which $4f_{\\rm rot}$ is compatible with the known DAC recurrence timescale. Thanks to simultaneous high-resolution CHIRON spectroscopy, we could identify another frequency $f_{\\rm env} = 0.10 \\pm 0.02$ c/d, caused by the circumstellar environment. Variations in the circumstellar environment are believed to cause the observed difference between the BRITE lightcurves.

    The cyt1Aa gene from Bacillus thuringiensis subsp. israelensis (Bti), whose product synergizes other mosquitocidal toxins, and functions as a repressor of resistance developed by mosquitoes against Bacilli insecticides, was introduced into the aquatic Gram-negative bacterium Asticcacaulis excentricus alongside the cry11Aa gene. The genes were introduced as an operon, but although mRNA was detected for both genes, no Cyt1Aa toxin was detected. Both proteins were expressed using a construct in which a promoter was inserted upstream of each gene. Recombinant A. excentricus expressing both toxins was found to be approximately twice as toxic to third instar larvae of Culex quinquefasciatus as transformants expressing just Cry11Aa.

    The pH-sensitive P(AA-co-NVP)Iclay hydrogels were prepared with the monomers of acrylic acid (AA) andN-vinyl-2-pyrrolidone (NVP) based on γ-ray irradiation technique. The influence of pH values of buffer solutions andcontents of clay and NVP on the equilibrium swelling ratio (SR) and compressive properties of the hydrogels wasinvestigated in detail. The results of swelling property tests showed that, with the increase of clay content, the SR ofhydrogels increases in the same buffer solution, and the SR of hydrogels with different contents of HTMAB-clay is higherthan that of P(A.A-co-NVP) hydrogels without clay. When the content of clay is 15%, the SR of P(AA-co-NVP)/clayhydrogel is 201 at pH=9.8, which is 1.23 times of that of the P(AA-co-NVP) hydrogel (164). In addition, the SR ofP(AA-co-NVP)/clay hydrogel is higher than that of PAA/clay hydrogel in the same solution. The compressive properties ofthe hydrogel were also examined. The results showed that the compressive properties of the P(AA-co-NVP)/clay hydrogelswere improved distinctly as compared to those of the conventional hydrogels without clay. When the content of clay is 15%,the compression strength of the P(AA-co-NVP)/clay hydrogel is 23 times of that of the P(AA-co-NVP) hydrogel.

    According to radiation protection theory, the radiation shielding properties of composites are closely related to dispersion condition of radiation absorbing materials in matrix. The more equably radiation-shielding materials dispersed in the matrix, the better the composites' shielding properties are. Rare earth ions have preferably absorbing ability for radiation due to their special electronic structures. From our early work, we know Sm(AA) 3 has good radiationabsorbing ability and excellent compatibility with polymer matrix. Furthermore, Sm (AA) 3 has double key structures which can in-situ react with polymer matrix in vulcanization process. This in-situ reaction can also help Sm(AA) 3 disperse better in the matrix. Based on these, we studied a new method to prepare Sm( AA)3/NR( nature rubber) composites( NR used as matrix), in which Sm(AA)3 dispersed very equably with tiny particle size. Both sulfur and peroxide exist in the system as crosslinking agent. The vulcanization process occurred at the temperature of 110℃ first and a certain degree crosslinking network formed in this stage, which we called pre-vulcanization process in this paper. In this stage sulfur was used as the crosslinking agent. Then continued the vulcanization process at higher temperature(170℃). The peroxide was used as crosslinking agent in this stage. According to reaction-induced phase decomposition mechanism, we studied the phase decomposition changing mode of Sm(AA) 3 in NR matrix of different crosslinking degrees. We also studied the influence of different degrees of pre-vulcanization to the dispersion condition of Sm (AA) 3 in NR matrix. The crystal-fusion status of both Sm(AA) 3 powder and Sm(AA) 3 in cured rubber were observed by DSC (Differential Scanning Calorimetry) and XRD (X-rays Diffraction). The dispersion condition of Sm(AA) 3 in cured rubber was observed by SEM (Scanning Electron Microscopy) and TEM (Transmission Electron Microscope).The studyresults show different

    Full Text Available Friction stir welding (FSW combines two plates by frictional heating at the interface with the localized plastic deformation within the material. In friction stir welding heat is generated by the friction between rotating tool shoulder and the plates to be welded. The heat thus generated results in thermal softening of the material. The softened material is then forced to flow by the translation of the tool from the front to the back of the pin. There it cools, consolidates and results in joint formation. In the process, strength of the joint and percentage elongation varies from the parent material. AA6101 is equivalent to AA 6061 and AA6063. At present AA6101 is used by the electrical industries only. A detailed experimental study has been done on AA 6101 to its utility as an Aluminum alloy for structural fabrication

    In automotive industry, sheet metal forming process play a key role with respect to economy and weight reduction ratio. In sheet metal forming, one of the operations is bending operation in which sheet will not go under sever deformation. The end components are made by applying the continuous load on the sheet in the bending process. In bending process, elastic limits of materials are exceeded, but flow limit thereof cannot be exceeded. Therefore, the material still keeps a portion of its original flexibility character. When the load is released, the material on forcing compress side tries to enlarge, whereas the material on tensile side tries to shrink. As a result, the material tries to spring back and the bended material by flexing slightly tries to open. Springback varies according to thickness of the material, material and process parameters, type of material, period when punch load stays on the material, dimensions of die, force applied, and bending radius. In order to make bending at a desired angle, springback amounts should be avoided. In the present work, experimentation on AA 6061 alloy sheet springback analysis has done with seven different rolling directions. Results are noted with respect to load, displacement, and die angle on the springback effect. It observed that springback affect is existed notably in the AA 6061 alloys with respect to die angle.

Anabolic-androgenic steroids (AAS are the most widely abused drug. Much of our knowledge of the psychological and physiological effects of human growth hormone (hGH and insulin has been learned from deficiency states. As a consequence of the Internet revolution, previously unobtainable and expensive designer drugs, particularly recombinant human growth hormone (rhGH and insulin, have become freely available at ridiculously discounted prices from countries such as China and are being abused. These drugs have various physiological and psychological effects and medical personnel must become aware that such prescription medicine abuse appears to be used not only for performance and cosmetic reasons, but as a consequence of psychological pre-morbidity.Keywords: AAS, cosmesis, growth hormone, insulin, performance, strength

  10. Solving the $R_{AA}\\otimes v_2$ puzzle

    For the past ten years $R_{AA}(p_T)$, the nuclear modification factor that encodes the suppression of high $p_T$ particles due to energy loss within the medium was fairly well described by many theoretical models. However, the same models systematically under-predicted the high $p_T$ elliptic flow, $v_2$, which is experimentally measured as the correlation between soft and hard hadrons. All previous calculations neglected the effect of event-by-event fluctuations of an expanding viscous hydrodynamical background as well as the soft-hard flow harmonic correlations in the experimentally measured $v_2$. In this talk I show how event-by-event viscous hydrodynamics (computed using the v-USPhydro code) coupled to an energy loss model (BBMG) is able to simultaneously describe soft physics observables as well as the high-$p_T$ $R_{AA}$ and $v_2$. Suggestions for future more differential calculations at the LHC run2 are made to explore soft-hard flow correlations.

    Watermarking using the command watermark{DRAFT, v2}.Are you an astronomer considering submitting a paper to an AAS journal (i.e., AJ, ApJ, ApJ Letters, or ApJ Supplements)? If so, this post is for you! Read on to find out about the exciting new things you can do with the AASs newest LaTeX class file, available for download now.Why the Update?AAS publishing has maintained a consistent class file for LaTeX manuscript preparation for the past decade. But academic publishing is changing rapidly in todays era of electronic journals! Since its journals went fully electronic, the AAS has been continuously adding new publishing capabilities based on the recommendations of the Journals Task Force and the needs and requests of AAS authors. The AASs manuscript preparation tools are now being updated accordingly.Whats New in AASTex 6.0?There are many exciting new features and capabilities in AASTex 6.0. Here are just a few:Tracking options for author revisions include added{text}, deleted{text}, replaced{old}{new}, and explain{text}.Based on emulateapjDo you use the popular class file emulateapj to prepare your manuscripts? AASTex 6.0 is based on emulateapj, rather than on the older AASTex 5.2 (though 5.2 is still supported). This means that it is easy to produce a double-columned, single-spaced, and astro-ph-ready manuscript. Since two thirds of the AAS journals authors use emulateapj, this transition was designed to make manuscript preparation and sharing an easier and more seamless process.Tools for collaborationsDo you work in a large collaboration? AASTex now includes new tools to make preparing a manuscript within a collaboration easier. Drafts can now be watermarked to differentiate between versions. New markup for large author lists streamlines the display so that readers can access article information immediately, yet they can still access the full author list and affiliations at the end of the paper. And author revision markup allows members of a collaboration to

    Platelet-derived growth factors (PDGFs) are important biochemical mediators regulating many physiological and pathophysiological processes, including promotion of the chemotactic recruitment and proliferation of cells involved in wound repair. Previously, homodimers of rhPDGF-AA protein were purified from Escherichia coli. However, eukaryotic proteins often contain posttranslational modifications, such as glycosylation, that are required for biological functions. In this study, an efficient method was established to purify a glycosylated rhPDGF-AA dimer from P. pastoris culture media by one step CM Sepharose ion exchange chromatography yielding about 20mg/L of over 95% highly purified rhPDGF-AA. Mass spectrometry analysis of the purified rhPDGF-AA displayed a molecular weight (MW) of 27,825.513Da, composed of a subunit with MW of 15,042.945Da and a subunit with MW of 12,904.374Da. The size difference is accounted for by differential glycosylation of the monomers. Biological activity of the rhPDGF-AA was confirmed by its ability to induce NIH/3T3 cells proliferation. The experimental procedure we have developed facilitates production of an active glycosylated rhPDGF-AA in large amounts for further research and drug development.

    The Boyd E. Christenberry Planetarium at Samford University (Birmingham, AL) offers family friendly, live, and interactive planetarium presentations that educate the public on topics from astronomy basics to current cutting edge astronomical discoveries. With limited funding, it is not possible to provide state of the art planetarium hardware for these community audiences. In a society in which many people, even young children, have access to high resolution smart phones and highly realistic video games, it is important to leverage cutting-edge technology to intrigue young and old minds alike. We use an Oculus Rift virtual reality headset running AAS WorldWide Telescope software to visualize 3D data in a fully immersive environment. We create interactive experiences and videos to highlight astronomical concepts and also to communicate the beauty of our universe. The ease of portability enables us to set up at Virtual Reality (VR) experience at various events, festivals, and even in classrooms to provide a community outreach that a fixed planetarium cannot. This VR experience adds the “wow” factor that encourages children and adults to engage in our various planetarium events to learn more about astronomy and continue to explore the final frontier of space. These VR experiences encourages our college students to participate in our astronomy education resulting in increased interest in STEM fields, particularly physics and math.

    A simple europium complex, Eu(TTA)3AA (TTA=4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione, AA=acrylic acid) was syn-thesized by a simple solution method. Then, two kinds of rubber matrix, nitrile-butadiene rubber (NBR) and silicone rubber (SiR) were used as the substrate for Eu(TTA)3AA to prepare fluorescence composites. The neat Eu(TTA)3AA complex showed the ability of self-polymerization when it was heated at 145 °C. It was found that the fluorescence intensity of the neat Eu(TTA)3AA decreased over 70%when the polymerization time was over 25 min at 145 °C. The results also revealed that the polymerizated Eu(TTA)3AA could be dispersed in nano-scale in two matrices and the luminescent intensities decreased 52%in NBR matrix, and 95%in SiR ma-trix compared with two relative compounds without crosslinking. To optimize the luminescence intensity of the composites, the Eu(TTA)3AA polymerization kinetic process in matrix was investigated in detail by controlling the temperature, the crosslinking agent, etc. The results showed that the peroxide could accelerate Eu(TTA)3AA self-polymerization in the rubber matrix, and therefore improved the dispersion, but not be helpful for the luminescence intensity enhancement. In addition, the relatively higher luminescence intensity in Eu(TTA)3AA/NBR in comparison to that of Eu(TTA)3AA/SiR might contribute to the interaction between nitrile group (-CN) in NBR and Eu-complexes, suggesting that the luminescence intensity of the composites also depended on the matrix characteristics.

  19. Depletion of spleen macrophages delays AA amyloid development: a study performed in the rapid mouse model of AA amyloidosis.

    Katarzyna Lundmark

    Full Text Available AA amyloidosis is a systemic disease that develops secondary to chronic inflammatory diseases Macrophages are often found in the vicinity of amyloid deposits and considered to play a role in both formation and degradation of amyloid fibrils. In spleen reside at least three types of macrophages, red pulp macrophages (RPM, marginal zone macrophages (MZM, metallophilic marginal zone macrophages (MMZM. MMZM and MZM are located in the marginal zone and express a unique collection of scavenger receptors that are involved in the uptake of blood-born particles. The murine AA amyloid model that resembles the human form of the disease has been used to study amyloid effects on different macrophage populations. Amyloid was induced by intravenous injection of amyloid enhancing factor and subcutaneous injections of silver nitrate and macrophages were identified with specific antibodies. We show that MZMs are highly sensitive to amyloid and decrease in number progressively with increasing amyloid load. Total area of MMZMs is unaffected by amyloid but cells are activated and migrate into the white pulp. In a group of mice spleen macrophages were depleted by an intravenous injection of clodronate filled liposomes. Subsequent injections of AEF and silver nitrate showed a sustained amyloid development. RPMs that constitute the majority of macrophages in spleen, appear insensitive to amyloid and do not participate in amyloid formation.
